Heyo! Let’s take this one step at a time~

Starting off, the lines section looks great! Your superimposed lines are smooth, have minimal fraying, and maintain a consistent trajectory. The ghosted lines/planes are quite confident, too. One thing I’ll recommend is plotting start/end points for the non-diagonal center lines of the planes. In doing so, you take care of the placement/perspective issue in one step, and execute the line in the next, rather than trying to do both at the same time. Of course, looking at your results, this doesn’t seem particularly necessary, but it doesn’t hurt to be careful.

The ellipse section looks equally strong. Your ellipses are confident and circular, and, even more importantly, continue being confident and circular as the difficulty ramps up in the latter exercises. Be careful not to rotate around them more than 3 times, however. Given the level of confidence here, I’d recommend sticking to 2, if you can. Try, also, to lift your pen off the page, at the end of those rotations, rather than flick it off. (The latter leaves a noticeable mark on your page.) Normally, I’d take this opportunity to jump into the specific exercises, offering a pointer here and there, but there’s not a lot (negative) to say about yours. I suppose I could mention that in some of the funnels, the minor axis doesn’t cut the ellipses into two equal, symmetrical halves, but that seems to be as a result of the construction of the funnel itself- something that’s difficult to get consistently right.

Instead, let’s talk about your boxes! Though it started off fairly strong, the rough perspective exercise shows considerable improvement. You’ve been careful in keeping your verticals and horizontals, well, vertical and horizontal, and the convergences are fairly spot-on, too. To take them further, spend a little longer on the planning phase, next time. I noticed that you went with a lot of your first guesses for this exercise, but that is not necessary. It’s perfectly acceptable, and even encouraged, to ignore your points if you think they’re off. Despite its size, this is a solid attempt at the rotated boxes exercise. The boxes are snug, and rotate quite comfortably. 4 of them are missing, however (the corner-most ones.) Finally, let’s talk about the organic perspective exercise. One thing I notice is that the foreshortening is sometimes a little dramatic. You’ll remember that dramatic foreshortening suggests an object that’s either really large, or really close to us- and as such, has no place in this exercise (particularly in the far off boxes!) I did, however, really appreciate the amounts of overlapping boxes, here. It can get a little confusing at times, which is why we recommend using some line-weight, to clarify which box is overlapping which, but that’s alright.

Overall, this is a really solid submission- I’m happy to mark it as complete.
