Hello and welcome! Let’s take this one exercise at a time, shall we?

Starting off, your superimposed lines are well done. They’re smooth, properly lined up at the start, and of a consistent trajectory. I’m very pleased to see so many of them on your page, but I do wish you’d drawn the arcing ones a little bigger. (I say this, because they’re a little lacking in confidence, but this is normal, because the smaller you draw, the harder it is to engage your shoulder for what you’re drawing.) The ghosted lines/planes are well done, also, and I’m especially happy to see that you’ve not forgotten to plot some start/end points for the non-diagonal center lines of your planes – most students do.

The table of ellipses exercise looks good. I’m glad to see such a variety to them (their degrees/angles, I mean), and all of them are smooth, rounded, and properly drawn through. The ellipses in planes look good, also. Despite these more complicated frames, they do a good job of maintaining their prior smoothness/roundness. You’ve also correctly chosen to prioritize that, even at the cost of accuracy, here and there. The funnels look great, too. Your ellipses are snug, and properly cut in half by their axes, but I’ll remind you that you’re only to add an ellipse if there is an axis, and frame, to align it to, and limit its size, respectively. Otherwise, what you’re looking at is an ellipse without a goal, which is not something that’s especially valuable for us, at this stage.

The plotted perspective exercise looks clean.

The rough perspective exercise starts off strong, and shows some nice improvement throughout the set. By the end, its convergences are on-point, and its linework really confident. I do wonder at how light it is, however. Though that taper at the end is nice, in the sense that it makes your lines look quite a bit more dynamic, you need to be careful that you don’t lift your pen off the page too quickly, so see if you can work on that a little.

The rotated boxes exercise looks great. It’s big (huge positive!), and though its boxes struggle to rotate at times, they’re snug. This is not always the case – in the back, especially, there’s the occasional problem – but the attempt is there, which is all that matters. Rejoice in the thought that, as we progress through the box challenge, you won’t have to decide between keeping them snug, or drawing them correctly, as you have here – instead, you’ll be able to do both. Until then, this is more than satisfactory.

The organic perspective exercise, too, is really well done. I especially like that you’ve got a lot of boxes that are cut off, as they’re really effective in suggesting a composition larger than the sum of its parts. Said composition is also helped by the construction, size, and foreshortening of your boxes too, of course, so nice work there, as well.
