Congratulations on finishing the first lesson of Drawabox! Overall you did a great job here, but I do have a bit to mention so let's break them down one by one. I'll write the most important things in bold.

Lines

Starting with your superimposed lines, these are looking good. Ghosted lines look correctly ghosted and confident too, and there are barely any arching. You've also demonstrated the same confidence in your ghosted planes with a great accuracy. Nothing much to say except keep up the good work!

Ellipses

Now with the tables of ellipses, you've demonstrated a great understanding of the concept in executing confident ellipses. The funnels also look great; you've managed to fit them snugly and aligned to the minor axis and carried the same confidence as in your tables of ellipses.

However, I saw that confidence faded in your ellipses in planes. While you did draw them snugly in the planes, you also ended up with some robotic-looking ellipses here and there, which can result from hesitation or a limitation on your pivot (like using your wrist instead). A confident execution leads to an evenly shaped ellipse, whereas hesitation leads to wobbling and uneven shapes just as it does for our lines. The fact that this is only visible in this exercise can mean that you're trying to hit all sides of the planes that you're forgetting to confidently ghost the ellipses. Remember, prioritize confidence over accuracy.

Also a quick reminder to not draw through your ellipses too much, as you did here a few times. 2-3 times is enough. Trying to correct your initial lines with more lines is not a good way to practice your confidence. https://drawabox.com/lesson/1/tablesofellipses/drawingthrough

Boxes

The plotted perspective has no problems, you've shown a good understanding of how to make 2 point perspective.

You've applied the ghosting method and lines extension correctly for the rough perspective. You also drew the front/back faces rectangular, which is correct for 1 point perspective.

As the notoriously most difficult exercise in this lesson, you've done a great job at doing the rotated boxes. You've rotated them pretty well (while making sure to move the converging lines) and used neighboring elements to deduce the next orientation of boxes, which is the whole purpose of this exercise.

Finally, organic perspective looks great as well. They look like they belong in the same page and the lines converge as they move farther away from the viewer. There are a few hiccups here and there where there are divergences that results in skewed boxes, but overall they're minor and they look pretty solid. Plus you'll get plenty of chance to experiment

Anyway, while you can practice more with your confidence in the ellipses in planes exercise, I think you've grasped the concepts of the whole lesson and ready to put them into practice in warmups. Again, congratulations and keep up the good work!
