Hey there Jjag, TA Meta here to look over your work, so let's get started.

Starting with your superimposed lines and these are looking great, they're straight and confident. I did notice on a couple of the curved lines that there's a certain amount of fraying on both ends, so make sure you take the time to line your pen up before executing. Your ghosted lines and planes again, straight and confident and not much to say here.

Next your tables of ellipses are looking fantastic. Your ellipses are a nice round shape and executed with a lot of confidence. If I had to nitpick, I'd say that you could've packed them more tightly against each other and there's a few instances where they pop out of their bounds, but I'd much rather see this level of confidence and accuracy to come in time.

Your ellipses in planes are more of the same, you've done a pretty good job of making them touch all four sides without sacrificing confidence for accuracy.

Finally, your funnels are looking pretty good in terms of confidence and alignment to the minor axis. You do seem to have gotten a bit loose with the spacing of your ellipses and they seem to consistently pop out the sides so this might be something you want to work on controlling. A couple of your ellipses are skewed off the minor axis, particularly in the one on the bottom right and you do seem to have a little bit of trouble controlling ellipses with sharper points on them - this is completely normal as we're used to doing such sharp little turns with our wrist, so make sure you work on driving this motion from the shoulder in your warm-ups.

Onward to your rough perspective and these are pretty good. You've done a good job keeping your horizontals parallel and verticals perpendicular to the horizon line here. I am going to guess that this is part of your original submission, as your line confidence here is a bit lower than I'd previously seen. This could also have been uncertainty in taking your lines and turning them into boxes, so make sure you take the time to plan out each of your lines. Also try not to reinforce the inner lines of your boxes as this can somewhat break the illusion.

Next your rotated boxes are itty bitty! Make sure you draw big so you give your brain space to work through spatial problems and fully engage your shoulder in drawing your lines. That said, this actually looks great, you've kept the gaps between your boxes nice and consistent and managed to capture the full degree of rotation here. There's some yuckiness with the heaviness and confidence of your lines but overall the exercise is well done.

Finally, your organic perspective is looking great, your compositions do a good job exploring 3D space with the variation in scale of your boxes. Your linework here is actually really nice, you've also applied line weight with a nice confident hand which is fantastic to see. As mentioned above, try not reinforce the inner line and most importantly, be subtle! Our brains really don't need much line weight to clarify what is in front and what is behind.
