    Hi there, I'll be looking at your work today.

    Organic Arrows

    • The rate of expansion/compression as the arrow moves towards/away from the viewer is done correctly.

    • There are some line confidence issues. The line that matches the initial line, the arrow heads, and the line weight around the arrow overlaps are sometimes a little wobbly. These lines should be done confidently with the ghosted method, so make sure to do this.

    Organic Forms

    • Ellipses/contour lines are almost always consistent with the center line.

    • The shape of the sausage forms are sometimes inconsistent. Ideally, they are two identically sized balls joined together without any bulging or pinching in the middle.

    • The ellipses occasionally have some execution issues, usually in line quality and overall shape. Remember to ghost thoroughly and execute confidently, just like the lines. Consider revisiting lesson 1's section on ellipses if necessary.

    • Some of the ellipses are not shifting their degree. This is vital to understanding how the form exists in space and how these ellipses represent the 3D nature of the form in perspective.

    • The contour lines are sometimes a little shallow, detracting from the illusion of the 3D form. This is a somewhat inconsistent problem, but be aware of it.

    Texture Analysis

    • The first two textures sometimes have a few areas that are defined by lines as opposed to cast shadows. This is best seen at the light end of the gradual texture. While it can be tempting to simply make a line to represent a shadow, it is usually not the case at the highly light areas, so be careful of this.

    • Otherwise, the textures look like they have a lot of thought and consideration put into them.


    • The silhouette is always broken when appropriate, which makes the texture stand out. This is very important and competently done.

    • A few of the textures do not wrap around the form properly. The straw and acoustic foam textures have this problem where they look flat at parts even though they are supposed to be covering a rounded shape.

    Form Intersections

    • This section is done very well, and feels like as if all forms are in the same scene.

    • The same thing about ellipse execution applies from the section with organic forms.

    Organic Intersections

    • This section is also done very well. Every form is supported and wraps around each other appropriately, and the shadows are cast correctly.

    • Some of the contour lines are a little shallow, just like the other organic forms exercise.

    Overall, this lesson's homework is done. Good work.

    HI there, and welcome back. You were gone so long that the 250 Box Challenge was revamped.

    Things that were done well

    • Good improvement in making the lines converge. It is great to see it get better and better consistently.

    • The face that is hatched is generally the correct one (facing the viewer).

    • Adding line weight to clarify which lines are on top is great.

    Things that could be improved

    • A consistent issue is line quality. Many lines are wobbly, and that caused some issues with how you extended lines (sometimes, they didn't match the original line that was placed). Consider revisiting lesson 1's section on lines if necessary.

      • Also, the hatching lines should be done in the same quality as your other lines.
    • Some of your lines are a little parallel. One of the points of the challenge is to reason about vanishing points and converging lines, so this detracts from the intention. Watch out for this in the future.

    • A few of your boxes are missing back corners and/or line extensions. This was more of a problem in the earlier sections of the pages, and was resolved at the end. Make sure that you have done everything you need to do before moving on, as all parts of box construction are important to learning.

    • There were a few boxes at the end that had malformed Y's, such as box 249. There should be at least a 90 degree angle between all of the lines. This leads to an issue where you have two point perspective as opposed to three point, and boxes in two point perspective defeats the purpose of doing arbitrarily rotated boxes in space (three-point perspective). It was only done a few times, but make sure you can recognize this difference.

    Aside from some of the issues listed, I think this is done. Good work.

    Imagine if we did what we did in the planes exercise of lesson 1 with each of the faces of a box. From the center point, you could draw a line sticking out perpendicular to the plane. For these 3 front-facing planes, all 3 of the lines that stick out would point out of the page in some way as opposed to pointing into the page (hence why they are front-facing). The shaded face should be on the plane with the line that points most directly to the viewer.


    It might also help to take a small box and rotate it around (the rate convergence of the lines does not affect how the planes face you). Hope that makes sense.

    Hi there, congrats on completing this challenge. I'll be handling your critique today.

    Things that were done well

    • The lines were confident and no wobble, which is great.

    • Hatching on the front face was applied, which shows thinking about orientation.

    • Almost all of your boxes demonstrated thoughtfulness and reasoning about 3D space. This is seen in the placement of the back corner, which is very difficult to do.

    Things that could be improved

    • The biggest issue is the diversity of the boxes. Starting at box 110 to around box 220, the boxes all had shallow convergence and roughly the same orientation (in particular, the angle between the lines of the Y are very similar between boxes). Ideally, you should try to draw boxes with varying convergences so that there is enough practice with all shapes and orientations of boxes with different VPs.

    • There seems to be a slight issue with overshooting the lines. Consider slowing down or keeping the end dot in sight.

    • Some of the hatched faces are not facing the viewer. This would show up every so often throughout the entire challenge, but boxes 162 and 226 are apparent examples of this.

    I think this was very well done. Just remember to slow down and vary it up for future boxes.

    Congrats on completing the 250 Box Challenge! I'll be looking at your work today.

    Things that were done well

    • There was very good improvement at around box 150 after some stagnation. I could visibly see where it clicked.

    • The hatching the front face was always done correctly, which shows an understanding on how boxes are orientated.

    • The lines were executed quite well, which is always a challenge while juggling box construction and estimating vanishing points.

    • I like the RGB line extensions. They make it much easier to visually parse several boxes that may be cluttered.

    Things that could be improved

    • The variety of boxes is fairly low. Generally, they have shallow foreshortening and are some thin rectangular or square box. The more experimentation there is with foreshortening, shape, and orientation you play with, the more your understanding of objects in 3D space will grow.

    • Extending lines in the wrong direction. I think you were more and more aware of this as you progressed, but it would appear irregularly even towards the end. This defeats the point of checking line convergences, so it's important to get it right. Review the section in the challenge (note that the challenge was changed a little while back) if it still occasionally occurs.

    • A lot of the boxes are parallel and do not converge to a vanishing point. This could be an issue with how the boxes are constructed (consider the angles between the lines) and some random error when placing down lines (usually solved with the fundamentals in lesson 1).

    • Consider adding some line weight to the outer edges of the box. It generally helps reinforce the structure and placement of the edges.

    Overall, I think you did well and were aware of your weaknesses. I think you are ready to move on. Consider drawing boxes for your warm-ups with some of this feedback in mind. Good luck!

    I've never used Pinterest before, but I can recommend Google Drive. The only problem is that it requires a Google account, but it will hide your email.

    I agree.

    Things that were done well

    • Strong improvement over time was seen. The first boxes had sets of lines that were rather parallel, which is a common issue, but at around box number 100, they started converging a lot more.

    • There was clear thought put into the construction of the boxes. Just like the previous item, boxes felt less auto-pilot after a certain point.

    • The back corner was placed well a lot of the time. This is probably the hardest thing to do in the lesson, so good work on that.

    Things that could be improved

    • Line fidelity. There is a recurring issue where a bunch of lines per page are not straight or have significant wobble. This is usually an execution issue, where there is not enough ghosting or shoulder motion, compounded with the difficulty of constructing boxes. Consider re-visiting the fundamentals in lesson 1.

    • The boxes with shallow convergence (i.e. VP is far away) tend to have one line converge too quickly. This is an issue mainly seen in the last 75 or so boxes, especially in the larger ones. Pay attention to the angles between lines, and that should help with seeing the boxes converge.

    • There was a lack of diversity in the boxes at the start and beginning, the worst offender being that central box in the last 10 or so pages. It generally improves understanding of 3D space if many different orientations of boxes are drawn, so don't forget to vary it up.


    • Hatching the front face is a great exercise to reason about which plane faces the viewer, reinforcing spatial reasoning.

    • Do not use Imgur since it's a crap website that constantly messes with ordering and occasionally disappears your images. Some of the early pages are out of order, and I am sure that you didn't do that intentionally.

    Overall, I think this is complete. There are areas that need some polishing, but there is ample time to improve. Good luck with lesson 2.

    Hi, I'll be taking a look at your work today. But before that, congrats on completing this lesson. The difficulty of constructing a box and doing it 250 times is definitely noteworthy.

    Things that were done well

    • Clear improvement was seen in your boxes. Starting around box 100, the issue with diverging lines is largely corrected.

    • Hatching lines were applied correctly. This is great and shows your understanding of which plane faces the viewer, and demonstrates understanding of 3D space.

    • A good variety of boxes was shown. Just like the previous item, having different boxes with different convergences shows the spatial reasoning.

    Things that could be improved

    • An issue that shows up every so often is that a box will have a parallel set of lines. The best way to fix this is to take your time ghosting and being aware of the angles between lines, since this helps in recognizing the VP the line is converging to.

    • The extra line weight is sometimes wobbly, detracting from the intention. This is usually a result of trying to match the original line and then not executing confidently, sort of a cart-before-the-horse situation. Thus, make sure that the extra line is confident, and that should help in making the lines match better.

    • The boxes with more rapid convergence (i.e. the VP is closer) tend to be done better than the ones with shallow convergence. It may help to start with boxes that have rapid convergence, and slowly make them shallower as you draw more boxes.

    • The hatching lines are generally well-done, but once in a while seem rushed (i.e. fraying, not parallel, overshooting). Just remember that they should be done with a level of execution expected of all lines in this course.

    I think you are ready for the lesson 2. Just remember to keep your line execution confident, and to review some of the fundamentals. Good luck!

    I think imgur may have messed with your images, because I can't see any of them in the link. Could you try another upload method?

The Art of Brom

The Art of Brom

Here we're getting into the subjective - Gerald Brom is one of my favourite artists (and a pretty fantastic novelist!). That said, if I recommended art books just for the beautiful images contained therein, my list of recommendations would be miles long.

The reason this book is close to my heart is because of its introduction, where Brom goes explains in detail just how he went from being an army brat to one of the most highly respected dark fantasy artists in the world today. I believe that one's work is flavoured by their life's experiences, and discovering the roots from which other artists hail can help give one perspective on their own beginnings, and perhaps their eventual destination as well.
