Hey, congrats on finishing the challenge! I'll be looking over your work.

Starting with your lines, although your line quality was pretty solid even in the beginning, by continuing to prioritize confidence further, you still managed to improve in this regard throughout the challenge, to the point where your boxes looked almost like they were drawn with a ruler. Your line weight got cleaner as well; instead of drawing thick lines that stood out on their own like in the beginning, you started to apply line weight smoothly and subtly.

I feel like you could've been more mindful with your hatching however. Even though your hatching lines got better as well, they were rarely as accurate as the lines on your boxes. They were usually shorter than needed and there were times where the lines wouldn't touch either edge of the box, implying that you weren't fully paying attention to where you placed your pen. These hatching lines obviously aren't as important as the lines of the box itself but they still help carry the illusion of depth. If we're not mindful of how we create every part of our constructions, we risk making them look unconvincing, thus making our drawings look 2D.

Moving onto the boxes, just like your lines, you seem to have improved greatly in this regard. Although you still have some lines that converge too early in your later boxes (mostly the inner line), your convergences generally got cleaner as you kept going.

On the topic of convergences, let me remind you that the mistakes in the inner lines are generally fine since they are mostly the representation of the accumulation of every small mistake you've done while drawing the box. I'd still like you to take a look at this diagram though. Also, if you want to minimize your mistakes with the inner line, make sure to take a look at this demo to see a different approach to constructing boxes.

You did a pretty good job with trying out different shapes of boxes as well. However, I'd like you to try out boxes with different orientations in the future, as shown here. You also extended your lines in the correct direction which is great.

One last thing that I'd like to mention is the fact that you used a smaller paper for this challenge. Although your line quality was pretty great overall, I think you would benefit from using a bigger paper and drawing big to fully engage your shoulders.

I don't think I have anything else to add! I'm sorry if the structure of this critique was rather awkward since I accidentally closed this tab while I was writing this critique the first time. Because of this, I had to rush through a bit the second time to make sure that I didn't forget to rewrite any point I've made earlier. There is still a chance that I forgot something though, so if you have anything to ask, feel free to do so on here or on discord by tagging me.

Overall, you did a great job with this challenge and you should feel free to move on to lesson 2, good luck!
