Welcome and congratulations on finishing the first lesson of Drawabox! I'm Mada and I'll be taking a look at your submission.

Overall you did an excellent job here, but I do have a bit to mention so let's break them down one by one.

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. I've seen some waves here and there, but they're minor and your accuracy will increase as you get more practice.

Ellipses

Now with the tables of ellipses, you've demonstrated a great understanding of the concept in executing confident ellipses. There are a few uneven shapes with the almost full circle ones, so keep them in mind as you're doing them in your warmups. The ellipses in planes are nice, you drew it confidently and snugly in their respective planes, and I like how smooth the 2nd page turned out.

The funnels are also looking great; you've managed to fit them snugly and aligned to the minor axis and carried the same confidence as in previous exercises. I have no complaints here as your ellipses will tighten as you get more practice.

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. Except for just one (which I assume is your very first box), 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 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. You may want to vary the rotation of the boxes more (vary the lines of the Y shape more; make one shorter and another longer, etc.) as they all look almost the same buuutttt... you'll have plenty of chance to experiment with them in the 250 box challenge.

Anyway, 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!
