Hey there, Piapal! The name's Keisari42, and I'll be the one to critique your Lesson 1 submission today. Before all else, congratulations on finishing Lesson 1 and starting your Drawabox journey!

Lines

Mostly, your lines look good. Specially in Ghosted Planes, you're doing a great job engaging your shoulder and drawing smooth, confident lines which should only improve with practice. However, in your Superimposed Lines it's apparent you lacked patience -- the majority of your lines present a lot of fraying on both ends. It's important you place your pen carefully at the starting point before making a mark, and judging by the sheer volume of lines you've made, I'm guessing you bit off more than you can chew. Patience is a virtue, and one of the core values of Drawabox -- if you're going to do that many lines, put as much effort into each one of them as you would if you were doing few. I'll be requesting revisions, reply with those.

Ellipses

You did really well with your ellipses! You're drawing through them more than 3 times occasionally, but that'd be nitpicking. Overall, they mostly look smooth, but some deformation can sometimes be seen, specially in the Ellipses in Planes exercise; keep in mind that having then be smooth and even is your highest priority, so don't let other factors take precedence over that. That being said, it seems each pass diverges a lot from the previous one on some of your ellipses (mainly in Tables of Ellipes), losing a lot of solidity. Once again, I'd like to emphasize how important being patient and giving your best is in this course -- are you taking your time to properly make use of the ghosting method?

Boxes

Your boxes are very good, and you've shown a proper understanding of the concepts and information presented in the lessons, and your line quality was preserved. However, I have a few things to comment on about your Rotated Boxes exercise:

Firstly, you seem to have missed the cornermost boxes in both of the bottom quadrants and seem to not have done the 180-degree reminder squares (https://drawabox.com/lesson/1/17/step3), but I'll let that pass. More importantly, you seem to have misunderstood how converging lines towards vanishing points work -- at least for the back corners. As the exercise page says, the perpendicular lines are where two of the three vanishing points for all boxes sit, with each of a box's set of lines converging towards one. You seem to have gotten the rotation aspect, but for most of your boxes, these lines don't converge properly, with the lines on the back corner instead being parallel to or even diverging from the visible ones.

To help, here's an edit of your rotated boxes showing how the lines of some of your boxes should converge; note how far off your back corners are: https://i.imgur.com/aF2OLsk.png

Of course, errors in the Rotated Boxes exercise are to be expected and you've in fact done much better than most people, so just keep that in mind for when you do it as a warmup.
