Hello there, Anya! I'm Keisari42 and I'll be the one to critique your submission today. Congratulations on finishing Lesson 1 and starting your treacherous journey in Drawabox! ?

Lines

For the most part, you did good! You're doing a great job at drawing your lines confidently -- however, I noticed that many of them arc noticeably. That may be caused by using your shoulder pivot rather than your shoulder pivot, which is one of the main points taught in Lesson 1; if you're sure you're drawing with your shoulder, then you might be naturally inclined towards arcing your straight lines, which you could work on by practicing consciously arcing in the opposite way on your warmups.

Ellipses

Once again, you did well! I don't have much to comment on about your ellipses themselves other than sometimes you seem to get pointy ends -- as long as you're drawing from your shoulder and prioritizing smoothness and confidence over accuracy, practice through warmups and future exercises should help you work on that.

However, I noticed you didn't submit your Ellipses in Planes exercise; did you forget to do it or was that just a mishap on the uploading? Either way, I'm requesting revisions and asking you to reply with those.

Boxes

You've gotten the concept! Your boxes are good enough, and you've shown proper understanding of the information presented. However, I noticed you seem to have redrawn some lines in the Rough Perspective exercise? That should not be done. One if the main points taught in Drawabox regarding markmaking is that while learning it's important to know to accept and deal with your mistakes; you are not to do multiple attempts on any given lines -- if you're not satisfied with the way you placed down a mark, at least throughout the course, you move on rather than trying to "fix" it.
