Hello there! I'll be giving you some feedback on your work. I'm a beginner myself, so apologies in advance if my wording isn't clear or if I make some mistakes.

LINES:

Very smooth lines! You made a clear effort to make each stroke in your Super Imposed page begin from the same starting point. There is fraying at the ends, but that's to be expected at this stage. Continue to practice these skills during your warm ups and keep a clear goal in mind when doing these. Eventually the fraying will diminish a bit. For your ghosted lines, you consistently hit the first dot and either overshot or very closely miss the second. Try to hit that second dot by stopping just before you reach the point. You could maybe even try to lower your speed just slightly to gain more control (not too slow that it causes wobble).

ELLIPSES

You have great ellipses. Just remember to draw from your shoulder, even when doing tiny ellipses. Your strokes are over all very confident. From here, I feel you should focus on tightening up your strokes and try your best to stay within the borders (keep your ellipses from overlapping with eachother, etc). However, be careful not to focus too heavily on this and end up warping your ellipses to keep within the border.

BOXES

Clean boxes. You have a few perspective mistakes but your perspective will improve when you tackle the 250 box challenge. I suppose one thing you should keep in mind is that your rotated box assignment lacked a spherical shape in it's end project. This is common though, this assignment isn't meant to be something easy. If you'd like to challenge yourself, after you finish the 250 box challenge, maybe go back to this and see how your understanding has changed by attempting rotated boxes again! This is, of course, optional.

CLOSING THOUGHTS

Great job. I think you showed good progress here and are ready to move on. Good luck! Also, if you have time, I'd appreciate it if you shot a critique or an agree on my assignment. Have a great day :)
