Hello Citriczart!
Congratulations on completing the first lesson! Completing this much work takes discipline. Also, your work is very good! Here is my critique. (I have only recently completed drawing my 250 boxes (the next step after lesson 1), so I am still a beginner as well. Feel free to take this critique accordingly.)
Your lines improve as the lesson progresses. They become more confident and straight and arch less. One thing I note is it seems you prioritize the line being the correct length over being confident or having accurate placement. According to the lesson ( https://drawabox.com/lesson/1/ghostedlines ):
"Level 1: Line is smooth and consistent without any visible wobbling, but doesn't quite pass through A or B, due to not following the right trajectory. It's a straight shot, but misses the mark a bit.
Level 2: Line is straight, smooth and consistent without any wobbling and maintains the correct trajectory. It does however either fall short or overshoot one or both points.
Level 3: Line is straight, smooth, consistent without any wobbling. It also starts right at one point and ends exactly at the other."
You make your lines straight (not arched, which yours sometimes are) before your direction is accurate, and then you must make the direction is accurate before worrying about the length. If you have any lines that are the right size, but are curved and off trajectory, you are prioritizing the wrong qualities.
I saw maybe one box on your ellipses page with floating ellipses, but overwhelmingly each ellipse is kept within the bounds and touching each other, without overlapping. So that's great! Also, a couple of the funnels, the line you have for the minor axes doesn't cut the funnel in to two symmetrical halves. But mostly they're good.
The organic perspective is really good. I notice that you didn't add any lineweight to indicate which of two overlapping was on top. If you practice trying to add lineweight to the correct edges, I think it'll help the viewer better place the boxes in space.
The strongest critique I have is that it seems to me you haven't completed the rotated boxes exercise, although you've started it three times. To get the full use of this exercise, you really have to attempt all 25 boxes as they appear in the example homework at the bottom of this page: https://drawabox.com/lesson/1/rotatedboxes (5 rows of 5 boxes each with the corners being the most extremely rotated). Without going to the full extremes of the rotation, you won't be able to get as good of a grasp of 3D space. Making the attempt is all the lesson asks, though, so no worries if it turns out looking wrong.
Good luck on your next 25 boxes, because after that there are 250 more! :D
Next Steps:
Complete the rotated boxes exercise with all 25 boxes. (It may look terrible with mistakes and that's fine.)
