Hello, I'm r0m1 and I'm a complete beginner, but I will try to make a critic :)

Superimposed Lines

You are executing your mark confidently, and maintain a confident, consistent trajectory for your strokes. You place your pen where the mark should start. The lines do not wobble, and there are no fraying at the begining of the lines. It seems correct to me.

Ghosted lines

It also seems correct to me: you are drawing the lines without hesitation. They do not wobble nor arc or bow.

Ghosted planes

Some of the lines look a bit arcs, but I think it is because the paper is arking rather than your strokes. The lines are still drawn confidently, so it's correct.

Tables of ellispes

You definitively draw through your ellipses 2 full times, and they fit snugly against the borders and they are evenly shaped. Correct again :)

Ellipses in planes

You draw through your ellipses two or three times, and they all touch the for edges of your planes. Plus, they all are evenly shaped.

Funnels

You have drawn through your ellipses - one of them has been drawn through more than 3 times I think, but It seems correct otherwise. Other than that, I think everything's ok: the ellipses are touching the edges of the funnel and they are aligned to the central minor axis line.

Plotted perspective

You used a ruler, as stated in the instructions. Note that some of the verticals are not perfectly perpendicular to the horizon. All the edges plot back to the vanishing points.

Rough perspective

You are working with a single vanishing point, in the middle of the frame and both the front and back of the frames are rectangular (there are some imprecision in the stroke but I don't think you misunderstood the exercise). You applied the line extension correctly and your strokes are confidently drawn with the ghosting method.

Rotated boxes

You followed the instructions and the core steps of the exercices: this is referring to laying out the vertical and horizontal axes, as well as adding the squares at the end of each axis (this helps remind the 180 degree rotations). The gap between the boxes are consistent.

I think you used the same vanishing point for all boxes, so they are not really rotating: when rotating the bowes at least one of the boxes' sets of parallel edges will have its vanishing point move - frequently it'll be two.

You draw through your boxes and all the boxes are drawn.

Organic perspective

You used the ghosting method to draw your boxes and the boxes sets of parallel edges do not diverge as they move farther away from the viewer. You did not leaned into particularly dramatic foreshortening.

From my beginner point of view, you did a pretty good job :) There are only a couple of details that could be improved, so you can be proud of yourself for completing this!
