Congratulations on completing the 250 Box Challenge! You did really well overall and I can see that you grew and learned a lot.

When I compare your first few pages to your last sets I can see that your mark making is much more confident and I see a lot less hesitation overall. As you progressed I can see that you did a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing point.

One thing I go notice is that you still struggle a bit with adding weight to your lines. Remember when you go to add weight to a line it is important that you treat the added weight the same way you would a brand new line. That means taking your time to plan and ghost through your mark so that when you go to execute it the mark blends seamlessly with your previous mark. This will allow you to build and create more subtle and clean looking weight to your lines. You should also apply this to your hatching marks which you appear to give less care and consideration to when compared to your boxes and the quality of their construction.

Finally while your convergences do improve overall I think this diagram will help you further develop that skill as you continue through Drawabox. So, when you are looking at your sets of lines you want to be focusing only on the lines that share a vanishing point. This does not include lines that share a corner or a plane, only lines that converge towards the same vanishing point. Now when you think of those lines, including those that have not been drawn, you can think about the angles from which they leave the vanishing point. Usually the middle lines have a small angle between them, and this angle will become negligible by the time they reach the box. This can serve as a useful hint.

Keep in mind what I've said here and you should continue to see improvement in your work. Congrats again and good luck with lesson 2!
