Hey! Let’s see here~

Your superimposed lines look good! They’re smooth, and of a consistent trajectory, but they’ll occasionally fray a little- see if you can spend a second longer on the lining up phase, next time. The ghosted lines/planes look great! I have 2 recommendations. The first is to make their start/end points a little smaller- the idea is that a perfect line should swallow them both. The second is to actually have some start/end points for the non-diagonal center lines of the planes.

Moving on to your ellipses, they’re generally solid, but you’ve gone around them too much. 2-3 times is the recommendation- I suggest 2. The table of ellipses exercise looks good. They’re snug, and of a consistent degree/tilt in a frame. In the ellipses in planes exercise they do a good job of touching all 4 sides of the plane, but never sacrifice their roundness to do so- that’s the way to go. Finally, in the funnels exercise, they’re quite snug, but the minor axis doesn’t always cut them into two equal, symmetrical halves. One cause of this is the construction of the funnel itself. It helps to add the minor axis last, so that it’s equidistant from the arcs. Extend it all the way, too, or, conversely, if there’s no more minor axis, stop there, rather than adding more ellipses. Also, don’t neglect to ghost these ellipses, rotating the page as necessary. If you’re not confident in their alignment, continue ghosting/rotating. You decide when to commit, so decide when you’re ready- no sooner.

Moving on to the box section, the rough perspective exercise looks good. It seems like you used a ruler for their front faces (this is incorrect), but that’s not a huge issue. The convergences improve nicely throughout the set. To take them further, I’ll give you a little hint. Because of the rules of perspective, the back face of the box is similar to the front face in shape, but not size (it’s smaller!) Meaning, if the front face is a square, the back face cannot be a rectangle. So, if your points suggest that it is, then they’re incorrect, so, rather than commit to them, try again. Solid attempt at the rotated boxes exercise. It doesn’t quite rotate, but this is expected. What’s important is to see it through to the end, which you have. Furthermore, the boxes are snug, and confident- nicely done. Finally, the organic perspective exercise looks fantastic! The sheer number of boxes, their consistent, shallow foreshortening, and their frequent overlaps all aid in its flow, and their convergences are quite good, too. One, fairly minor, thing, is that line-weight (I’m assuming that’s what that is, not automatic reinforcing), is applied to the silhouette of the box, not the inner lines. You’ll have plenty of time to get used to that in the box challenge, however. Off to it!
