Strengths:

Confident lines on ghosted planes and ellipses in planes

Ellipses touching most corners in planes

Most ellipses in tables are not overlapping

Most lines are going back very close to the vanishing point on the ghosted perspective exercise

Rotating boxes - good rotation of boxes, and boxes are close together

Organic perspective - most boxes are converging well or pretty close. Good variation in size and shape of boxes.

Challenges:

Ellipses in funnels are all the same width. Ellipses in the center should be thinner than ellipses on the sides, to indicate depth. Remember that as a shape moves farther away from the viewer, its back edge rotates toward the viewer, so that more of its face is visible to the viewer.

Vanishing points are off of the page on the plotted perspective exercise.

Rotating boxes - boxes toward the top and bottom center are much more rectangular than original box in the middle center.

Organic perspective - some boxes are not converging quite enough, some lines which should be receding are a bit to parallel
