Congratulations for completing the 250 Box Challenge!

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. You drew your boxes at a pretty good size and with a variety of orientations and foreshortening. You also start to do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points!

I noticed that you still struggle a bit with applying your extra line weight. When you go to add weight to a line it is important that you treat the added weight the same way you would a brand new line. That means employing the ghosting method here as well. You should be taking your time to plan and ghost through your mark so that when you go to execute your extra line weight, it is done confidently and so that it blends seamlessly with your original mark. This will allow you to create more subtle and clean looking weight to your lines that reinforces the illusion of solidity in your boxes/forms. Extra line weight should be applied to the silhouette of your boxes, as shown here. I recommend that you try adding your extra line weight in no more than 1-2 pases so that you can easily identify mistakes in your work. This diagram should help also you better understand how to properly apply your extra line weight.

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 15 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 marks, 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.
