Hi, I'm Laura and I'll handle your lesson 1 critique.

Lines

To start, your superimposed line have been done well, there's little to no wobble and no fraying on the starting side.

Likewise the ghosted lines, all look confidently made, there's some minor arcing that could be improved by making sure you use your shoulder and trying to compensate with intentional arcing to the opposide side.

Ghosted planes all look good as above.

Looks like you understood the assignment well and executed it to good effect, any inaccuracies will diminish with practice.

Ellipses

Table ellipses and planes are both done well, ellipses drawn through, and funnels look decent, there's some alignment that could be improved, but it shows correct intent. I'd also recommend to try reducing the angle of the ellipes as they go farther out, as shown at https://drawabox.com/lesson/1/18/step3, it helps with practicing different angles which will come into play in later lessons.

Overall the ellipses look good, there's a visible focus on smoothness, getting the circles to touch all 4 sides will improve with time, and it's all done with correct intention.

Boxes

Plotted perspective looks fine, there's some misalignment with vertical lines not being totally vecrtical/perpendicular to the horizon, try giving yourself more time to align the ruler next time.

Rought perspective was done well, the line extensions go to the horizon and the ghosting method was applied in all lines, although as the previous exercise, you should give yourself a bit more time to align each of the vertical and horizontal lines, as quite a few of them are slanted.

Your rotated boxes turned out great, all of the steps of the exercise were followed correctly, though the rotations aren't perfect, you put in good effort. Spatial problems like these are quite difficult, and this exercise is meant to be an introduction to it, so you'll get better at them as you go through the other lessons.

Organic perspective shows a good variety of boxes, all using the ghosting method with visible confidence, and the convergence is mostly consistent.

Summary

Overall, you did a great job and understood the concepts taught, showed confidence in your strokes, and built a good mental foundation for the rest of the course.

I'm marking it complete, feel free to continue to the 250 box challenge.

And you may add all of the exercises of this lesson to your pool of regular warmup exercises.
