Hi, I'm Laura, I'll do your critique.

Lines

Superimposed Lines - Starts with fraying only one side but has fraying on both sides in the second page, give yourself more time to align your pen onto the starting point of the line, not doing that ends with an aimless line that doesn't really teach you much. Also make sure you're using your shoulder to do your strokes and look at the end point of the line to help reduce fraying and wobble(also experiment with slowing down a bit, you'll get less fraying).

Ghosted Lines & Ghosted Planes - A bit of arcing, but otherwise good, can be counteracted with more consciously using your shoulder to execute the strokes, and trying to intentionally arch the line in the opposite direction to cancel it out if it persists, and I see that sometimes you missed the starting point again, try to be more careful an give yourself more time to put your pen down on it.

You understood the core principles, keep the tips in mind and try to implement them in yoru warmups.

Ellipses

Table Ellipses - Drawn through 2-3 times as instructed, but there's often a sizable deviation from the first rotation, try slowing down and focusing on ghosting through the ellipse as closely as you can, using your shoulder is very important here, try to minimize movement from the elbow or wrist(This section helps with more explanation https://drawabox.com/lesson/1/16/remember).

Ellipses in planes - Same as the previous one, but try to not worry as much about fitting the ellipses inside plane exactly, as a smooth and round ellipse is better than one that accurately fits the plane.

Funnels - The ellipses are right on the line, and mostly fit their borders as they should, though there are a few funnels that have inconsistent fitting, but again, try to focus on smoothness and following the rotation through the second time, more important initially than fitting them exactly.

Overall you understood the assignments, but rereading and rewatching this section https://drawabox.com/lesson/1/16/remember and implementing the tips should help improve your understanding and execution.(Also, try giving yourself a bit more time for each ellipse, ghosting them before putting them down helps too)

Boxes

Plotted perspective- Good, though there are some lines in the back that aren't perfectly vertically, give yourself a bit more time to align your ruler on these.

Rough perspective - Pretty good, make sure to use the ghosting method and give yourself more time to put down each point, as some of the lines have noticeable angles to them

Rotated boxes - You kept the boxes tight(though the spacing is a bit inconsistent sometimes, more time to put down the dots will help), rotated them well, and drew all of them, good.

Organic Perspective - You understood most of the ideas of the exercise, though the boxes here often have diverging sets of lines, I'd recommend you read through the exercise and watch the video on it again, then on your own try to do one more section keeping in mind that each sets of lines of a box should converge, giving yourself more time to put down the dots too.(https://drawabox.com/lesson/1/organicperspective) I won't request a revision though, as you'll get plenty of practice with the 250 box challenge on getting the convergences right.

You understood the first three exercises and part of the fourth, going through it again should help.

Summary

You understood the concepts taught, though had some issues with making the Y boxes, but the 250 box challenge should help out with that.
