Hey, Blunder. Congrats on finishing this lesson.

You have a very good work here. The things that concern me the most is that some of your lines seem to arch a bit. Remember that the motion for drawing them should come from the shoulder. If you end up mixing some elbow motion, they tend to arch a bit. This is more noticeable on your longers ghosted lines, but it also happens on some of your ghosted planes.

Another thing I notice is that in some cases you draw over the same line more than once, specially on your boxes exercises. Avoid doing this. It hides your mistakes, making them harder for you to identify them.

Overall I think you did a very good job here and are ready for the next challenge. Good luck!
