Heyo! Let’s see...

Starting off, your lines look quite good. There’s a tiny bit of arcing to your ghosted lines, so be mindful of that. (The recommendation is, usually, to arc in the opposite direction.) Also, in the ghosted planes exercise, I’d recommend placing start/end points for the non-diagonal center lines.

The ellipse section is really good! Your ellipses are smooth, rounded, and actually quite accurate. The only issue I notice is in the funnels exercise, where the degrees of your ellipses will sometimes decrease as you move away from the center. You’ll remember that they should either remain consistent, or increase.

The box section continues your perfect streak, though there’s a couple of minor things. The first is that you shouldn’t correct an incorrect line. This, of course, refers to redoing it entirely, but also to extending a line that stops short. Try to live with your mistakes. Outside of that, and some tiny foreshortening issues in your organic perspective exercise (the foreshortening should be shallow, as per the instructions), this is a fairly solid section, and a fairly solid submission. Well done!
