Hi Gadyulanovsky, Im gonna go through your submission!

First of all, I can clearly see a lot of growth on your work, you not only got better at convergence, you are also making bigger and more confident boxes and lines, though there is still room for improvement!

First thing that calls my attention is that you are having some trouble with the back corner, welcome to the club. Check this construction method next time you are wwarming up with some boxes!

Another thing caught my eye more on your last boxes is that there are quite a few lines that are curving slightly, now this is usually a sign that you are using your elbow more than your shoulder when drawing your lines, remember to consciously use your shoulder to draw so you can get a better line quality. Talking about line quality, Im seeing that your lineweight is slightly wobbly in a lot of cases, now this is not good- Whenever you are applying a mark in this course, that includes ellipses, curves, straight lines and, well... line weight, you should be always ghosting them and prioritizing confidence over accuracy. Accuracy will just come with time and practice, so dont worry too much about it just yet, just remember to take your time ghosting your lines.

One last thing I want to touch on is that whenever your are extending your lines to their vanishing points, you need to take into account the whole set of lines that are extending towards that same point. If you just relate your line with one of the lines that go towards convergence, you are not seeing how all the set relates with each other and they start looking a little odd. I know how confusing this sounds, so here is a diagram you can check out from time to time and it will end up clicking!

As I said, there is a lot of growth in this challenge and I think you did a great job, so Im gonna go ahead and mark it as completed! Keep up the good work.
