The exercises are all dated from October 2019. Did you give up back then and decided to come back? Genuinely curious as to what happened.

Lines: They look good for the most part. There was little variation on the ghosted lines, you could've tried much longer and shorter lines. There is some curving and arcing on the ghosted planes and sometimes they undershoot, which can be more troublesome than overshooting, depending on the circumstances.

Ellipses: Most of them are decent, though you'll want to try and close them properly, not leave the points hanging in the air. This is valid for all 3 exercises, but more noticeable on the table of ellipses, where the second pass also often strays too much from the first. The center line in most funnels isn't well aligned with the borders, it's often slanted, so it's hard to tell if your ellipses would've been "cut" in half. The good is that you managed to get most of them well contained within the arced borders.

For the ellipses on planes, the main problem is the second pass getting way off mark from the first, but you usually manage to maintain most of the ellipse within the borders, which is good.

Perspective: Some of your lines on the rough perspective are not ideal, with some arcing or curvature. The important thing is that you understood the principle, even if some edges went way off point, others got really close to VP.

The rotated boxes look very good, the edge looks curved, the only problem are some lines that you tried to fix. That's the problem with "fixing" lines, they really stand out.

On the organic perspective, the first page doesn't seem to follow the "farther away" thing, mainly on the first 2 frames, as the last boxes are larger than the ones in the middle. You probably realized this, as your second page got the boxes properly shrinking, save for a few along the middle.
