Hi, I'll be giving you my feedback today :D

Super Imposed Lines

I think you show a lot of confidence on making the line. That's good! I see that there are some lines where it doesn't start at the proper starting point. I mean the starting accuracy doesn't really matter that much, but positioning it correctly helps to reduce that automatic movement we do when we draw, making us a bit aware.

Ghosted Lines

Hey, you lines are pretty straight, that's a good thing. All you need to do is to work on the accuracy, don't worry, even I make that mistake.

Ghosted Planes

We all got that shaky day sometime, but I think my main feedback is to not draw it too close like the first page. But, I believe you can fill in a lot more shapes for both pages. It's probably just my personal preference but I think it's better to go overboard with the lines than to finish a little early. I think Uncomfortable has a tips to stop early, which is to lift your hand completely. But that's just me :D

Table of Ellipses

I think you are having trouble with the smaller ellipses, it overlaps with both the border and the ellipses inside. Though I gotta give you one thing, your ellipses is pretty confident. Mine was bended when I did this exercise. While the idea to go fast is correct, I think you just need to slow down or be aware to make an effort so that the the line would meet the first point you start. I don't know the correct speed, but try to find where you are most confident and most accurate speed when drawing it :D

Ellipses in Planes

Same critique with table of ellipses, I think you should work on making sure the line meets the first point you start. Your accuracy improved since the last one, less line overlap with the border of the planes. So that's good!

Funnels

The outer funnels seems to be the part where you seem to be having the most trouble. The center one was pretty accurate, but it looked like they don't differ much in term of size when compared to the outer one. Try to aim closer to the border :D Maybe make it more extreme if you want to practice next time. This could be done by making the center much smaller.

Plotted Perspective

I don't know why there are some lines that are not confident when you are supposed to use a ruler. Try to hold the ruler more firm next time :D

Rough Perspective

First of all, try to make the VP line straight and all the way, from one side of the page to the other. Personally, I find it much easier to understand with a clear line dividing the sky and the ground. Second, you need to draw a line from each point of the box to the VP with a ruler for this exercise, that way you can learn from your mistake. I can't really judge how accurate your point are without those line. I'm assuming it's a bit off like everyone. Also, try to put the dots of the initial square carefully, make sure not one dot stands up too much.

Rotated Box

You didn't rotate enough, use the guide at the end of each axis. It maybe a bit better to rotate too much rather too little, because in the end the goal of this exercise is to expose us to uncomfortable drawing angle so that we are used to it. Also, please use a ruler so that you can make a straight cross for the + axis. It will help guide you when rotating.

Organic perspective

It's fine to have the box all wobbly, but I wish you fit in a bit more box that way you can have more practice.

My main feedback overall is that you are confident. Just make sure to use a ruler next time when making lines from the box to the VP. In the 250 box exercise, you are gonna need a ruler to make sure you can learn from your mistake. I wish you luck on the 250 boxes exercise.
