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 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, however you have quite some arching with your lines, especially with the longer lines. This is a common issue that can have many different causes. At the end of the day, our brain does have to make certain corrections for the fact that all of the pivots of our arm (wrist, elbow, shoulder) result in an arc rather than a straight motion. So, while the pivot you do will most likely result in an arc, you have to correct them consciously so it becomes straight. Make sure that you ghost while pivoting from your shoulder, and try to intentionally arc your lines to the opposite direction to counteract the natural curve. This constant correction you make will eventually become natural as you get more practice. Read more here: https://drawabox.com/lesson/1/ghostedlines/arc

I'd like to add a little bit too that you're still leaving a lot of space in your ghosted lines and planes. While this is not an issue with your later exercises, do keep in mind to fill the page next time.

Ellipses

Now with the tables of ellipses, you've demonstrated a pretty good understanding of the concept in executing confident ellipses. The ellipses in planes are nice, you drew it confidently and snugly in their respective planes. The funnels are also looking great; you've managed to fit them snugly and aligned to the minor axis.

There are honestly still some wobbles here and there, but you had quite an improvement as you go along the exercises that I believe you just need more time and practice to execute more even, tight, and most importantly confident ellipses. A confident execution leads to an evenly shaped ellipse, whereas hesitation leads to wobbling and uneven shapes just as it does for our lines. That said, be more confident, and make sure you're allowing yourself to draw from your shoulder.(https://drawabox.com/lesson/1/ellipsesinplanes/deformed).

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. The problem I want to direct you to instead is the decreased confidence in your lines. I see you're trying to correct your lines, and there are even chicken scratchings here and there that resulted from it. Remember that at the end of the day, these boxes are just a bunch of lines. So, take your time and apply the ghosting method to each line as thoroughly as you can.

As the notoriously most difficult exercise in this lesson, you've done a decent job at doing the rotated boxes. You've used neighboring elements to deduce the next orientation of boxes, however you could've done more with the rotating of the boxes. It's very common for students to confuse rotation with convergence of the boxes. When rotating our boxes, at least one of the boxes' sets of parallel edges will have its vanishing point move - frequently it'll be two. If our boxes have the same vanishing point, then they're not rotating. (https://drawabox.com/lesson/1/21/notrotating). Again, this is very common and understandably difficult at first, so don't think too much about it and keep practicing.

This applies to all exercises: do not correct your lines by going over it with more lines. This will make your mistake stands out even more with how bold it is, and generally is against the concept of executing planned confident lines throughout this course. Unless it's waaaaay off the trajectory, accept the mistake and trust your muscle memory that it will get better with time and practice.

That problem is fortunately almost absent in your organic perspective exercise. The lines are executed more confidently here. The boxes 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 have plenty of chance in the 250 box challenge.

While I've gone through a lot of major points that you need to keep in mind here, you did demonstrate a consistent improvement throughout the exercises. I think you've grasped the concepts of the whole lesson and ready to put them into practice in warmups. Do keep in mind the points I've gone through and review the parts if you need to. Remember, be confident. Again, congratulations and keep up the good work!
