Hey Mars, I'll be your TA today so let's get started.

You got a lot of good mileage in with your superimposed, but you're still lacking a bit of confidence. This also continues in your ghosted lines. Keep practicing using your shoulder to make your marks and to ghost as much as you feel you need to so that you can execute confidently. So I don't keep harping on it - it is a common thread throughout all of your work so we will need to keep improving that line confidence.

Your ellipses are showing some good glimmers of confidence here, meaning it's definitely in you, it's just a matter of repetition/mileage. Your ellipses in tables are struggling moreso because of the extra constraints they have, but you are still being mindful of trying to keep orientation consistent and everything packed in space to leave no room for ambiguity. Your ellipses in funnels aren't too bad, just the draw through passes could definitely be tightened up. I see you didn't post your ellipses in planes, but that's ok because I was going to assign a page of that for redos so we'll talk about that later.

Your plotted perspective is fine, but when hatching make sure to do it neatly and not scribble - it would be better to leave it empty rather than haphazard hatching. The same goes for your rough perspective boxes. The orientation of your rough perspective boxes is good - horizontals parallel to the horizon, verticals perpendicular, and depth lines converging appropriately. Your line work is showing signs of improvement here.

As we move on to the rotated boxes I'm glad to see you pushed through and did the best you can. All we want for our students is that effort, since it's expected to be way over your current abilities and it's just to introduce these new concepts to you. That being said there are some key things I want to point out to further cement key concepts

Adjacency - Your adjacent lines are pretty far apart so you can't properly utilize them as perspective guides. This is a really useful technique so make sure you're understanding it and can properly leverage it.

Rotation - Your boxes are not rotating but rather skewing and shifting over, so give this gif some more attention and try to internalize how the rotation is driven by the vanishing points moving along the horizon.

Scale - Your scale isn't bad here. Definitely bigger vertically than horizontally. The reason drawing big is important is because it gives your arm room to fully use your shoulder and it gives your brain room to work through these spatial puzzles.

Watch out for that sloppy hatching though - each line should be ghosted and executed confidently. They are no less important.

Good start on your organic perspective boxes. You are exploring the space well with lots of boxes and motion in them. Your sense of perspective is still young, but will improve with mileage of the box challenge. You did a good job when you overlapped your forms and scaled them down. These two things cause the brain to perceive the forms as occupying a single space and sells the illusion of depth on the page, respectively. These two things really are key to the illusion of three dimensions on a two dimensional plane of paper.
