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. However, you're starting to curve and wobble your lines a bit in your ghosted planes. You might still be hesitating here, or limiting your pivot for some reason (usually by unconsciously using your arm or wrist as the pivot instead of your shoulder). Do keep reminding yourself to use your shoulder, and prioritize confidence over accuracy. They will get better as you get more practice, but you do need to keep conscious of what you're doing right/wrong and tweak it accordingly on your next attempt.

I also noticed that you didn't put the start and end points when you bisect the planes horizontally and vertically. This results in floating lines, like this: https://imgur.com/a/Ud2O6tR. Do not forget to always plan your lines first when ghosting, even though you already kind of know where they should be.

Ellipses

Now with your ellipses, you've generally done a great job at executing confident smooth ellipses, but I do have some stuff to talk about here. First of all, sometimes you're not really hitting the sides of the planes in the Ellipses in Planes exercise, nor fitting them snugly in the Tables of Ellipses and Funnels, making them look "floating" on the page. While accuracy is indeed less important than confidence, this is the next step that you have to really use your ellipses as you want it to. Try to touch all sides of the plane, and make the ellipses fit in snugly against each other for the Tables of Ellipses exercise. I'd also like to remind you that you need to draw through your ellipses for about 2-3 times, as you sometimes forgot to do this and draw them in one pass instead. Remember that these goals are there for you to practice your accuracy, so do reread these parts in case you might forgot about it:

Keep working on your ellipse confidence as some of your ellipses here look a bit choppy that might result from some hesitation. Again, a quick reminder to be more confident, and make sure you're allowing yourself to draw from your shoulder (https://drawabox.com/lesson/1/ellipsesinplanes/deformed).

Boxes

You've shown a good understanding of how to make 2 point perspective in the plotted perspective. I did see some skewed back vertical lines here and there, which is usually caused by an accumulation of human error as you plot more and more lines. I assume that's the case and you understand that every vertical line is straight in 2 point perspective. Even if the points are not aligned correctly, try to find a middle ground and draw it as vertical as you can.

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 used neighboring elements to deduce the next orientation of boxes, but I think you could've rotated the boxes a bit more. It's very common for students to confuse rotation with convergence of the boxes, like this: https://imgur.com/a/gd10hkK. 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)

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. Like you said, you could try to vary the boxes more in size, shape, orientation, and rotation to make them vary more and allow you to practice more types of boxes. I believe you'll be able to do so more confidently as you go through the box challenge, so make sure to experiment with the boxes a lot as you do it!

This will get more relevant as you get to the box challenge, but any hatching from this point on should also be done with the ghosting method. It will make your stuff cleaner and more practice is always good! Try to cover the whole area of the box with consistent spacing.

One last thing I want to mention is 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.

Anyway, I think you've grasped the concepts of the whole lesson and ready to put them into practice in warmups. Remember to keep practicing your lines and ellipses confidence. Again, congratulations and keep up the good work!
