Hello, I'm r0m1, and I will try to make a critic of your work. First, congratulation for completing the 1st lesson! Well done!

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

The ghosted planes are are missing (I assume you re-used them for the ellipses in planes). I think should have presented them without the ellipses but anyway, they seem correct to me. The lines are still drawn confidently, so it's correct.

Tables of ellispes

You definitively draw through your ellipses 2 full times. Remember to make them fit snugly against the borders, some are not! 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. A couple of them are a bit deformed, but that's minor. Good job!

Funnels

You have drawn through your ellipses, so It seems correct. I think everything's ok: the ellipses are touching the edges of the funnel and they are aligned to the central minor axis line (one is a bit misaligned, but that's minor). Well done again!

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. Do not forget to use the ghosting method from the shoulder, as some lines are a bit wobbling.

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 could be more consistent, but it seems ok to me.

You used different vanishing point for all boxes, so they really rotating.

You draw through your boxes and you did not forget any. This is pretty godd overall.

Organic perspective

Your strikes are done confidently and and you did not leaned into particularly dramatic foreshortening.

The boxes sets of parallel edges do not diverge as they move farther away from the viewer.

From my beginner point of view, you did a pretty good job :) There are a couple details that could be improved, but overall it's good! Well done!
