This is my first time critiquing so hopefully it's okay! I'll do it in sections so it's clear.

Lines: The Draw-over lines look good. The longer lines arc a bit but I think that's normal. For your ghosted lines, it's better to overshoot a little bit than to undershoot. Don't be afraid to make that mark! You got a better hang of this when drawing planes. Overall, looks solid.

Ellipses: Ellipse tables look good. I think you had an issue with the tail of the ellipse going off either too inwards or outwards of the ellipse, so watch out for that. The ellipses in funnels tilt slightly, when they're meant to be straight and symmetrical. But this is also a common error, and not too major.

Boxes: Rough perspective boxes, I can see you going back to fix your lines sometimes. This is discouraged. Any line you make should be treated as correct and used from there. Really good effort on the rotated boxes. For the organic perspective, I'm sure you noticed that some boxes have far-planes that are larger than their near-planes, which Uncomfortable talked about in the video. When you do your 250 box challenge, make sure your lines don't diverge and avoid having parallelogram or rhombus like shapes.

Overall it looks good. I think you'll fix your box mistakes when you move on to the 250 box challenge!
