Good job! Your lesson look good! Here's my critique, I hope it will help:

Superimposed lines:

Your superimposed lines look great! However, I think you were going a bit slowly when you where marking them since they look a bit wobbly. Don't forget to ghost your lines before drawing them, and when it's time to draw them, do it quickly! Accuracy is less important than confidence in this case.

Ghosted lines:

It's the same case with your ghosted lines. They are too wobbly and they could have benefited from a more direct line. Ghost your line, prepare your arm, and mark the line in a single quick shot!

Ghosted planes:

Your ghosted planes are great! Your issue with the precedent lines is less visible there but you still shouldn't forget that they have to be drawn quickly. Your ellipses look good but don't forget to draw them from 2-3 times, not more.

Table of ellipses:

Your table of ellipses is nice, the ellipses are not drawn more than 3 times and that's good!

Funnels:

When you're drawing your funnels, don't forget that there should be a sense of symmetry in them. The symmetry is present in most of the cases but there shouldn't be this big ellipse on the top of your page. The funnel should work like a mirror, your ellipses from one side should be the same as the ones from the other side.

Rough perspective:

Don't forget that your VP should be on the horizon line. Your lines look good, don't try and correct them: many of the lines of your boxes look messy because you went over your lines with your pen to try and correct them and that's not a good idea. When you make a mistake, don't add more ink to it, it will only draw the attention to the mistake. Your perspectivee is gonna improve a lot when you're gonna do the 250 box challenge.

Rotated boxes, organic boxes:

Impressive! The exercises look good, I don't have much to say about them. Just one thing: Don't try and correct your mistakes! Don't add more ink to them. If you make a mistake, just let it be.
