Great job on completing the box challenge!

I think you've improved a great deal over the set. I'm going to go over it a bit.

First of all, I think that the main issue your boxes have is that they are a bit wobbly. Just like in lesson 1, remember that confidence is more important than accuracy. So don't be afraid if your line misses the dot, the most important thing is to make that line confident and smooth.

And same goes with lineweight. When adding it, use a single superimposed line, ghosted and drawn with the shoulder. Don't trace over the previous line you did, and don't overdo it, it has to be subtle.

You've applied hatching and the line extension method to most of your boxes, but not all of them. The line extension method is very important for progressing, so In the next boxes you do, be sure you apply it correctly.

You mostly apply it correctly, though they are a few instances where you miss, like the boxes 147 and 237, so remember that lines should aways be extended away from the center for the Y
