Hi, I'll be handling your critique. This is not my first language, so sorry for any broken English.

Lines: You did a great job with the lines exercises. Superimposed lines feels good, no fraying at the starting end. It seems you're still hesitant about failing the accuracy, which I completely understand. But remember: smoothenes and flow are more important than accuracy. If you fail the dot, but your line has a good flow, you succeed. Accuracy comes with time. You can try to draw the line faster; I mean, after ghosting and planning it, you put the pen at the paper and draw it faster, not worrying too much about where it will falls.

In the Ghosted Lines, I can see that there's a little arching at the end of the lines. Probably because you're too worried about hitting the dot. To fix this, you can try lifting the pen when reaching the dot. You'll overshoot it, but your line will be fine.

Ellipses: Tables of ellipses seems a little bit rushed. Make sure to take the time to ghost it and plan, so all the ellipses inside the section look almost the same. But you drawing through them twice, which is good.

In Funnels, remember that the middle line represents the minor axis of the ellipses, so it must cut them in two equal parts. Some ellipses there are a bit tilted, and some others are not touching each others side.

Ellipses in planes are fine. But remember that you don't need to try to make the ellipse fit in the shape of the square.

Boxes: There are some issues with Rough Perspective. You plotted the lines from the vanish point to do the boxes, which is not what the exercise asks for. What you should do is to use the VP as a reference to draw the boxes, but not plot them. After you drew all the boxes, you use a ruler to extend the lines from the boxes to the horizon line, to check how off you are. Also, I think that you should put more boxes on each scene. Check the exercise page again, so you can better understand.

Rotated boxes is pretty good! The rotation is fine. Just the line quality that seems hesitant, so what I said regarding lines can apply here.

Organic boxes are fine too. The lightweight is something you should be aware of. Just add one superimposed line in the ones that crosses another. But I think you did a great job.

I'll ask for you to do one more page of the Rough Perspective. Check the exercise's page.

You did a great job, the first Lessons are always the hardest. So, congrats!
