Congratulations for completing the 250 Box Challenge!
From what I can see your line work is well done and your boxes are coming along well. As you progressed through the challenge your lines steadily became straighter and more confident looking overall.
In the future I would recommend that you add extra line weight to your boxes as an additional step. Adding extra line weight will help reinforce the illusion of solidity in your forms. 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 taking your time to plan and ghost through your mark so that when you go to execute it the mark 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. This is something that you will improve with consistent practice, so make sure that you include this step in your regular warm ups. You can also read more about this here.
I noticed that throughout many of your boxes, you 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, we should be drawing it 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.
I think this diagram will help you as well. So, 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 you move on to lesson 2 I am going to have you draw 30 Additional Boxes. What I will mainly be looking at is how your sets of parallel lines converge towards their shared vanishing point. Make sure to visit the links I have left you and follow all the steps. I also want to see you applying extra line weight to these boxes as well.
Good luck!
Next Steps:
30 Boxes as mentioned in the critique.
