Nah, that’s fine! No issues with the pen either, no worries! Let’s start from the beginning, then~

Your superimposed lines look good! They’re smooth, all lined up on the left, and of a nice, consistent trajectory. The arcing lines are solid, too, though next time I’d draw them a little bigger (easier to ‘unlock’ the shoulder that way). Nice work on the ghosted lines/planes, too. These are all confident, and I especially like that you’ve not forgotten to plot start/end points for the non-diagonal center lines of your planes (most students do!)

The table of ellipses exercise starts the ellipse section off well. You’ve got a very steady hand, and your ellipses are nicely rounded, and drawn through. You’ve got a good variety of degrees/angles, too, which is great! The ellipses in planes do a good job of maintaining this same degree of confidence, despite these more challenging frames. I’m very pleased to see how boldly you’ve drawn some of these bigger ellipses – nary a thought about what would happen if you missed. That’s how it should be! – accuracy is no concern of ours. Nice job with the funnels, too! Here, I’d perhaps spend an extra second on each ellipse, to make sure that it’s properly aligned to its minor axis, but it’s not a huge issue anyway. Your ellipses are confident, and snug – good work on both accounts.

The plotted perspective exercise looks clean. If you’re worried about some of those back lines, they’re off because of accumulating errors elsewhere in the box. It’s not something that you have much control over, so I wouldn’t worry about it! The rough perspective exercise starts off strong and shows some good improvement throughout the set. Your boxes here are quite ambitious, and their lines are all confident, and properly converging. Nice work with the rotated boxes exercise. It’s missing 4 boxes (the diagonal ones), but what’s here is solidly constructed. I appreciate that you’ve stuck with a lot of these, despite obvious difficulties, and especially that you’ve approached them so analytically! It has paid off~ The organic perspective boxes are very well done, too! Their construction is solid, and they also flow quite well as a result of their consistent foreshortening. The increase in size is at times a little inconsistent, however, but this is not a huge deal.
