Hey there, Will! So really great job getting throught the whole challenge.

Your line work shows a good deal of improvement throughout the challenge, although I would recommend that you continue to focus on your ghosting technique during warm-up. There is still a slight wobble in your lines that you can iron out with this technique. Likewise, I urge you to avoid going back over your mistakes with another line as this draws the eye. This is because an additional line increases line weight rather than covering up the mistakes.

As for your convergences, these become more consistent as well! By the end, I don't see very many stray convergences. However, I also don't see a lot of variation in your foreshortening. In most cases, your lines don't converge very much and in some, they diverge. With boxes in perspective, your correction lines should always converge, whether it's dramatically or a more shallow grade.

Take a look at this set of notes. It goes over the angle of the lines as they approach the box and how keeping an eye on this relationship can help your box lines converge correctly. Likewise, considering each line according to the lines with which it shares a vanishing point rather than the lines with which it shares a plane or a corner will achieve the same effect.

Overall, you did good work here but I think you can push this further. Refer to the section on foreshortening on the site.
