Congratulations on completing lesson 1! It was a real pleasure to review your submission. Let's go over each section and see your progress!

Lines

Good job not fraying on both ends, and I like the work you did with curving lines.

Ghosted lines look generally excellent. There is a bit of wobble in the lines, but this will improve with time. Keep practicing!

Excellent work on ghosted planes as well. I would recommend trying more extreme planes -- that is, ones that are very far away from being rectangles. This will help you practice ghosted lines of greatly varying lengths, and it's also fun to fill the paper with planes of widly varying shapes -- almost like a jigsaw puzzle.

Ellipses

Your ellipse tables look very good. There's a little bit of overlapping between ellipses, so you might want to go slightly slower, making sure to position your hand so it's right above the boundary line between the circle you're currently drawing and the next circle. This will also help when you "overshoot" the boundary, as you did on occasion like in row 3 of column 2 in the first ellipse table page.

Excellent work on ellipses in planes. Be careful that your lines don't wobble. Your ellipses are about as good as they come.

Your work in keeping the ellipses inside the funnel boundaries is all but perfect. Focus on making sure that the minor axis of the funnels divides each ellipse cleanly in two. Sometimes you allow your ellipses to skew, especially in the small funnel in the top right.

Excellent work on plotted perspective, and same thing for rough perspective.

Good work on rotated boxes.

Good use of line weight on organic perspective, and I also like how you obscured the parts of some boxes with others.
