I did catch myself squinting a little :P, but no stress! Let’s take this one exercise at a time shall we?

Your superimposed lines look great. They’re smooth, properly lined up at the start, and of a consistent trajectory. Practicing some arcing lines would’ve helped you, too, since the motion would have been good prep for the ellipses, but that’s alright. The ghosted lines look nice and confident, too, though their start/end points are a little large. They’re in a much better place in the planes exercise, though I notice that by page 2 they turn to lines, almost. I usually see points as small lines when the student is rushing their work, so be careful not to fall into that trap! Anyway, beyond that, your work is confident, so no stress.

The table of ellipses exercise looks good. There’s not a great deal of variety to your ellipses, and there’s the occasional spacing issue, too, so you’ll want to ghost for a little longer, but the ellipses themselves are smooth, rounded, and properly drawn through, so you’ve got most of it down. The ellipses in planes, too, are quite confident, and I appreciate how boldly you’ll miss your frame, sometimes! It’s more important for us that our marks are confident, than accurate, so it’s good to see that you’re one that same page – keep it up! Do, however, be careful not to go around your ellipses any more than 3 times; that’s the max. Nice work on your funnels! There’s some spacing issues here, too, but the ellipses are properly upright, and cut in half by their respective axes, so the bulk of the exercise is looking good.

The plotted perspective exercise is nicely done, though you should’ve used a ruler for your hatching lines. Also, be careful that your back lines are perpendicular to the horizon, as per the rules of 2 point perspective. If your points suggest that they’re not, that’s because of the accumulation of small errors, so the best thing to do then is to simply estimate the position of your back lines. The rough perspective exercise is well done, though it seems like you stuck with a lot of your first guesses here (which, though close, could be better if given a chance to be improved, so try not to be in too much of a hurry). Good work on the rotated boxes exercise. The hatching here is a little sloppy (I’m guessing wrist?), but the boxes are snug, and they rotate quite nicely – both up front and in the back! – so the bulk of this exercise is looking well. Save for the overshooting (it seems that you’ve figured out the direction of each line, but not where both of them intersect, so each extends arbitrarily, hoping to meet the other), the organic perspective exercise is well done. Your boxes here are properly constructed, and they flow well as a result of their size and foreshortening, too. Good work.
