Hello, Strudl! I'm Keisari42 and I'm here to critique your submission for Lesson 1! First off, congratulations on finishing Lesson 1 and, more importantly, nice keyboard.

Lines

You're making good use of the Ghosting Method! Your lines look good, mostly straight, smooth and confident. That being said, hesitation, arching and a bit of wobbliness can still be seen. You seem to be on the right path, but I'd like to restate that confidence is a higher priority than accuracy, that your accuracy will improve with time and practice as long as you make confident marks, and that overshooting is preferable to unconfident lines. You may want to experiment with making your marks with greater speed, as that could potentially help with making them smoother.

Ellipses

Your ellipses look GREAT! I have nothing to say about them. They're smooth, even, confident and you're drawing through them 2-3 times. Just keep up the good job and they will improve with practice.

Boxes

Overall, your boxes also look great and you've shown proper understanding of the concepts taught here. That being said, are the front planes of your boxes in Rough Perspective drawn with a ruler? Differently from Plotted Perspective, only the horizon line and the frames are to be done with straight edges. If they're not, damn good job with those lines. Your Rotated Boxes look really good, although I'd like to note the corner-most boxes don't need to necessarily have visible top planes. Your Organic Perspective homework looks good -- your issue with it might be the inconsistent convergences or how they might look inorganic, but it'll improve as you practice and gain a better understanding of 3D space. If you want specific advice, I'd suggest you think harder about the spacing or the distance between the boxes, and that also applies to your Rotated Boxes.

Overall, this is a great submission. I'm marking this lesson as complete, and not forgetting to add those exercises to your warmups, you may proceed to the 250 Box Challenge. Congratulations and good luck!
