Congratulations on completing the 250 Box Challenge!

You did really well overall and I can see that you learned a lot by the end of the challenge. Your boxes look cleaner and better constructed by the end and you do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points.

One thing I notice when looking at your boxes is that you tried to add additional weight to some of your boxes. For the most part you did an okay job of this though in some areas I can see that you struggled a bit. 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.

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.

Again, you did a really good job overall and if you keep in mind what I have said here you should continue to see improvement. Good luck with lesson 2!
