Hello! I will be taking a look at your 250 box submission.

The first thing to point out is the improvement in convergence after completing the challenge, it appears that your spacial reasoning skills have improved well, so the challenge has done its purpose. I would like to point out your strong points and what needs to be worked on to help you further improve in the future on warm-ups.

The things you have done well here are the experimentation with different kinds of rotations with each box, as well as a diversity of distinct parameters like initial Y lengths and dramatic and shallow foreshortening. It is also great to see that you have started using hatching and line weight later in the challenge. Indeed, it is optional and extra work, however they are great tools to use for later lessons as they help us reinforce the form. Other improvements are your line making, the wobbling has been reduced to almost a perfectly marked line with no deviation from its path. Still, make sure you are practicing it in your warm-ups, as these skills can be quickly lost without practicing often.

Now for the things that need improvement. Your convergence has gotten better compared to where you started, but a recurring problem seen in your boxes is the convergence in pairs as well as a back corner that is not following the same vanishing point from its sets. This can be worked on by understanding the relationship between each line in every set, as shown here To paraphrase from official critique: the inner lines will be similar, assuming you don’t build a long box. These lines will vary depending on the distance of the vanishing point relative to the box; further away, the lines become more parallel. They however do not diverge or are completely parallel in three point perspective.

Finally, a few things you could have done better. That being the previously mentioned line weight and hatching. Both of these were used, but the hatching was done sparingly. Starting from the beginning would’ve given you more mileage. The hatching was rushed a bit, so the lines didn’t turn out smoothly. Remember to ghost each and every line you are about to mark, including the hatching. Also, the line weight is a little too pronounced at times. Remember to be subtle, so one superimposed line is visibly enough for our subconscious to pick up and keep more structure to the form. Also remember that it should only be done at the silhouette of the form.

With that out of the way, I have seen enough to conclude that this submission can be marked as complete. Congratulations on completing the box challenge. It is a lot more work than most people think, and its completion shows you have a great desire to learn and push forward with the course. As always, remember to incorporate this exercise into your daily warm-ups to keep your skill sharp and to makes sense of the image I provided of the box’s angles if you haven’t already been paying attention to the angles. Feel free to rest or move on to lesson 2.
