Congratulations for completing the 250 Box Challenge! You did a good job on the challenge overall. I can see you made some good improvement with the quality of your mark making. Your lines steadily become straighter and more confident looking as you progressed through the challenge.

While your mark making has improved, I do see that you still hesitate in some areas. This is likely due to prioritizing your accuracy over creating a smooth, confident looking line.

Just remember that the confidence of the stroke is far and away your top priority. Once your pen touches the page, any opportunity to avoid mistakes has passed, so all you can really do is push through. Hesitation serves no purpose. Mistakes happen, but a smooth, confident mark is still useful even if it's a little off. If the line is wrong, we leave it and move onto the next step. Accuracy is something that you will improve on as you continue working through Drawabox and practice ghosting.

Now, while it is important that you use the ghosting method of each mark you make while doing Drawabox one thing you can try to help with ending your marks closer to where you want them is lifting the pen off of the page rather than stopping the motion of your arm. You can do this with extra line weight as well. I would also recommend that you read this comment by Uncomfortable, where he talks more about hesitation. You can also reread this section from lesson 1 about arcing.

Some of your boxes were drawn a bit small. Part of the reason for the 5-6 boxes per page rule is so that students have enough room to draw their boxes larger while having room to check their convergences. By drawing your boxes very small you limit your own ability to execute your lines from the shoulder confidently, which affects the quality of your mark making. Drawing bigger also helps engage your brain's spatial reasoning skills, whereas drawing smaller impedes them. It isn't a problem if your line extensions end up touching other boxes on the page so long as the boxes themselves do not touch or overlap. This should give you enough room to draw your boxes at a larger, more useful size.This, along with varying the foreshortening and orientations of your boxes, will help you get the most out of the exercise.

I did see that you were checking some of your convergences incorrectly.

Checking your convergences is an important step so you should always take your time and make sure you are extending your sets of lines correctly. Noticing and identifying mistakes is a major part of the learning process. Checking your boxes for mistakes is how you know what areas you need to address so that you get the most out of each exercise.

Your line extensions should extend away from the viewer and towards their implied vanishing point. You should do this for all three sets of lines that make up your box. They should extend from the center of the Y (from step one of your construction), out along the Y's arms. Be sure to visit the link for more information and for examples that you can use as reference. You can refer to the diagrams in this link if you are ever confused or uncertain.

For some of your boxes, you appear to have purposely tried to keep your sets of lines parallel on the 2D page, drawing them all to an "infinite" vanishing point. As explained in this section, because these boxes are oriented with us looking at the corner of the box, you should be drawing your boxes in 3 point perspective - meaning with 3 concrete vanishing points, each set of lines converging towards a real point in space, even if that point is far off and the convergence is gradual. At no point in the instructions does it state that you should draw your boxes without any foreshortening. All of the boxes you draw will have some foreshortening even if the convergence is very gradual. The circumstances in which vanishing points go to “infinite” as discussed in lesson 1 are only in specific orientations that run parallel to the viewer. In this exercise we are working with completely random rotations and so those cases are exceedingly rare. You can also watch this video I made where I demonstrate how I approach drawing boxes.

To clarify, when I say "sets of parallel lines" or refer to your sets of lines as parallel, I am referring to lines that are parallel in 3d space not parallel on the page. If you remember from lesson one, the core principle of perspective is that when we draw a 3d form on a flat surface those lines that are parallel in 3d will now converge towards a shared vanishing point on the page.

Which means your sets of lines will not appear perfectly parallel on the page. Think about how those lines converge, do not purposely try to keep them parallel on the page.

I think this diagram will help you as well. When you are looking at your sets of lines you want to be focusing only on the lines that share a vanishing point. This does not include lines that share a corner or a plane, only lines that converge towards the same vanishing point. Now when you think of those lines, including those that have not been drawn, you can think about the angles from which they leave the vanishing point. Usually the middle lines have a small angle between them, and this angle will become negligible by the time they reach the box. This can serve as a useful hint.

Before moving onto lesson 2, I am going to have you draw 30 additional boxes.

For these boxes you will do the following:

• Use the ghosting method for every mark you make, including hatching and extra line weight

• Draw all of your boxes in 3pt Perspective

• 5 boxes per page maximum

• Check all of your convergences as per the instructions

I will mainly be looking at the quality of your mark making to see if you are employing the ghosting method correctly for all of your mark making, including extra line weight and hatching. I will also be looking at your boxes to make sure your sets of lines are not being kept purposefully parallel.

Make sure you visit every link I have left for you and reread the challenge instructions in their entirety before beginning your revisions.
