Hi, hope I'm not too late to critique your work!

  • Your line work and hatching lines are done pretty well.

  • Though you struggled a lot with convergences at first (a lot of the lines were diverging, rather than converging), your convergences improved so much throughout the challenge.

  • Your back/inner corners look pretty good with this improvement.

  • Though, the back lines (the lines you wouldn't normally see) on some sets converge too rapidly toward the center line (the line you draw when making your Y). Before making any line in a set, try thinking about how the line would converge in comparison to other lines of the same set (as shown in this diagram: https://i.imgur.com/8PqQLE0.png). This is because the key thing to remember with drawing boxes is that any lines that are parallel in actual space will appear to converge to the distance to the human eye (and in turn, appear to converge to the distance in your drawing).

  • Other than that, great improvement.

  • I suggest not repeating any strokes, even if the first attempt didn't go as planned. Repeating strokes will just result in a highlight of your mistakes. Instead of repeating strokes, just move on and aim to not make the same mistake. Ghost for one line, and plan the line/ghost the line well before making the stroke.

  • Throughout the challenge, you've drawn every box with a fair amount of variation on its dimensions (length, width, and height), angle, and foreshortening.

  • I would suggest experimenting with more drastic dimensions/sizes and angles of boxes you're not very comfortable with when incorporating the boxes into your warm ups. Also continue experimenting with rates of foreshortening.

  • Here's a diagram with different angles of boxes: https://imgur.com/Kqg6uMX. (Obviously don't copy them, just glance at some enough to start drawing boxes from angles you feel you need practice on)

To sum up what you can work on:

  • Try to think of each line in a set & how it would converge in comparison to other lines of the same set (so you can work on your back lines converging)

  • Do not repeat any strokes, even if you messed it up

  • Experiment with the dimensions of the box, and the angle of the box
