Hi!

The superimposed lines: Your lines are confident; therefore, they're shown without wobble in lines and arching lines. However your curve lines are a little bit wobble. I understand the curve lines are more difficult than the straight lines because we can't see it because of our drawing hand. Keep practicing it regularly.

The ghost lines: The line at the ending point are curved in some lines. Keep in mind that we don't want a curve on a straight line. We don't focus on the accuracy rather than confidence and straight. Practicing the ghost method before drawing.

Table of Ellipses : There are some ellipses are overlapped and not tucked each other.

The ghost planes and the ellipses in planes: I see your attempt to draw ellipses contacted to 4 corners. That's good triumph.

Funnel : They are quite symmetrical.

The plotted perspective : I don't get why you crosshatched some boxes. Normally we mark the plane with slanted lines from edge to edge as shown here. https://d15v304a6xpq4b.cloudfront.net/lesson_images/1e4a234c.jpg

The rough perspective : The point is that the width lines should be parallel to horizon and height lines perpendicular to horizon. Most of your lines are not straight. In this course, we have to ghost before draw. Don't be rush to draw.

The rotated box: For me this one is not easy. I went back to watch the video and draw after the instructor every line. And then its shape is better.

Tho organic perspective : In my opinion, you drew too much boxes until it becomes confused. The purpose of this exercise is to know about far and near object. The far object should be smaller than the near object to the viewer.
