Hi congrats on completing the challenge. I'll be looking at your submission today. So starting off this is a really great submission. Your linework is very good and this is all very well though out and ghosted and your accuracy is very high. Your hatching is also very well done and not rushed so great work all around. Even your initial boxes are looking extremely solid. You are pretty clearly already at a point where you understand how box convergences work and while you aren't always hitting the mark perfectly you are generally close enough to where your boxes are coming out consistently solid. Still have a look at this graphic as this is always something good to think about when drawing a box. https://i.imgur.com/8PqQLE0.png

I can also see that you started experimenting with adding line weight to your boxes and that is good to see. There is still a lot of room for improvement on this front so keep working at it. You also might want to try working on exercises where you take one box and try and rotate it a bunch while keeping the proportions intact. You are at the stage where you need to be adding a bit more of a challenge to your box drawing practice. Overall, this was a fantastic submission with a very good understanding of the material and your improvement with your boxes is going to be much more gradual at this point. I'm going to mark this as complete and good luck with lesson 2. Keep up the great work!
