So you finished lesson 1! Great job! Let's take a look at the results:

Superimposed Lines

These are decent enough, but I notice quite a bit of fraying at the beginning. Make sure to keep the pen steady when you begin a stroke and always begin from the same place. I also don't notice a lot of attempts where you use curved lines. This is important to showing your understanding of the lesson material.

Ghosted Lines

These are simply OK. The wobble on these is quite noticable and runs a little wide. This seems to indicate that you perhaps weren't in a proper position to be drawing. And come to think of it your use of a clipboard does worry me a little. Try to work on improving your flow in future warmups.

Ellipses in Planes

I don't see this exercise anywhere! I can't critique something that doesn't exist.

Tables of Ellipses

These are fine, but the wobble inherent to your drawing is still noticable here. You could have used a bit more variation in terms of the patterns and degrees of ellipses attempted.

Funnels

This one is interesting because not only do your ellipses not seem as tight as before, you've actually got the degrees backwards from how they would normally be. You see, the exercise calls for you to increase the degree of the ellipse with distance, not decrease it. Otherwise I can't fault it much. You did your best.

Plotted Perspective

You placed your vanishing points at either end of the horizon line, which makes it harder to see. You could have drawn a lot more boxes and played with vanishing point placement more. Make sure to outline the boxes a second time and mark the near plane like the lesson material states you should do.

Rough Perspective

Your boxes have no foreshortening whatsoever! The lines are parallel and it's more of an oblique projection more than anything else. The far plane should be a smaller version of the near plane, which should have been marked by the way! At least you followed from the edges of the form rather than the vanishing point. You'd be surprised how many people get that wrong...

Rotated Boxes

Every box appears very similar, indicating you did not shift the vanishing points at all. The drawing looks very flat as a result, though this exercise is difficult to begin with. Don't beat yourself up over this marred attempt.

Organic Perspective

This feels really flat! We're not drawing shapes here (something that's gone into more detail later) we're drawing forms. And that means you have to believe in the secondary world the page is presenting to you. Watch that foreshortening, and remember to vary the rotation on the z (forward) axis. I know you can do better!
