Howdy, TA qzhans here!

Before we begin, I just want to congratulate you on giving those 250 boxes a good ol’ pen and ink smackdown. It is a MASSIVE undertaking and you’ve joined the prestiged club of its completers.

You’ve diligently drawn through all your boxes and extended every single last line out to check your errors, and your boxes have been better for it. Indeed, I can see quite a good improvement in terms of intuitive understanding of convergence throughout the set.

I also like how you've used line weight to reinforce the silhouettes of your boxes and help them pop out. However, there are some places where you’ve reinforced the lines inside the boxes, which doesn’t make sense since they are not supposed to be visible to the eye and are further back. Remember to keep it to the silhouette for this exercise.

Additionally, you have drawn a lot of your boxes quite small. I would say 2-6 boxes is a good number per page, as you want to do some especially big ones. This also allows you to do very flat or long boxes, which you should try. (Unless this is A3 paper, in which case these are perfect)

The one thing I do want to address is linework. I touched on this a little bit in the reinforcing section but there seems to be a tendency to redraw lines when they go astray. Remember that doing this actually draws eyes to any mistakes you make. If you mess up, just play around it; it’s a good habit to develop. You’ve actually for the most part applied this really well when reinforcing lines on the silhouettes, with very smooth, confident strokes, which tells me that the technical ability is there, but sometimes the mindset slips up.

Overall, very solid submission. I feel very at ease waving you onto Lesson 2!
