Starting with your superimposed lines, these are really quite well done. They're straight, confident, and generally what we like to see in this exercise. I did notice that occasionally you had fraying at both ends so make sure you take the time to line your pen up with the starting point to limit this to one end of the line.

Your ghosted lines and planes are also well executed - straight, confident, and fairly accurate. Not much else to add here, good work.

Next to your tables of ellipses and your ellipses are smooth and confident. You've done a good job keeping them packed in there tight for the most part, but I did notice particularly on the smaller ellipses that this spacing got a bit loose, so make sure you're trying to keep them butted up against one another.

Your ellipses in planes are looking quite good - you've kept your ellipses confident (with a few exceptions) and managed to hit the four sides of the plane most of the time. There's a few instances where they pop out the edges, but confidence should always come before accuracy, so this is a bit of a nitpick.

Finally, the ellipses in your funnels are pretty well aligned to the minor axis. There's a few instances of skewing here and there, but nothing too egregious. I did notice that you got a bit loose with the spacing on some of your funnels so again, make sure you're trying to keep them nice and tight.

Next your rough perspective is looking good. You've made a clear effort to keep your horizontals parallel and verticals perpendicular to the horizon line. I did notice a slight drop in your line confidence here, which we see quite often when students are first presented with this exercise, so make sure you're taking the time to plan and confidently execute each of your lines. Your estimation of perspective here is pretty good, where it strays, tends to be in expected ways such as boxes further from the vanishing point being less accurate.

You've done a good job on your rotated boxes keeping the gaps between the boxes tight and consistent. You've managed a fair amount of rotation but not quite tucked in those outer boxes far enough for the full range. This is pretty normal as our brains tend to actively fight against rotating our boxes too far, instead preferring to follow the vanishing point of the previous box rather than having this slide along the horizon line (axis). That said, you've done a pretty good job overall and this exercise is designed to introduce students to a new kind of spatial problem that might not have otherwise considered.

Finally, your organic perspective compositions are off to a good start with these generally conveying a good sense of depth in each scene through your variation in the size of your boxes. Don't be afraid to draw more boxes and possibly overlap some of these to even further push that illusion of depth. There are naturally some divergence issues with your boxes however this is something you can tackle in the 250 box challenge.
