Small heads up: for future submissions, be sure to place the pages in the order that they were done. It'll make critiquing your work a smoother process overall.

Your lines are off to a decent start; Starting from superimposed lines and going to ghosted planes, you've developed your ghosting technique fairly well already. I notice some wobble here and there, which you'll be able to improve as you refine your ghosting and stroke-making further, and some redone lines as well; remember to commit to all your strokes, even when you make a mistake. Also remember to draw from your shoulder if you aren't already. The only other thing I can say about your lines is that I see a number of cases where you either overshoot or undershoot your target; again, you will be able to refine this with time and practice. Continue to experiment with your ghosting speed to see what works best for you.

Your ellipses have a bit more room for improvement, but you still have a solid start here. On the tables exercise, I see some instances of ellipses overlapping and some instances of them extending out of their bounds. None of the cases are a major overlap - they just overlap on one of your two-three runs of the ellipse - but it should be kept in mind. You still draw your ellipses confidently, which is good.

The funnels are pretty good overall; the ellipses are split evenly by the minor axis, they change size and degrees, they stay within their bounds for the most part... I don't have any criticisms here. Nice work.

The boxes are, in my eyes, where you have the most room for improvement.

Firstly, I notice that you haven't submitted any work for the plotted perspective exercise. Remember to do all the exercises for a Drawabox lesson so that you have completely worked through the material. As for the other exercises...

Your rough perspective has room for improvement, but it's not a bad start. A couple lines don't feel like they're fully horizontal/vertical, which can hurt the sense of physicality. Horizontal lines should be parallel to the horizon while vertical lines should be perpendicular to it. This can be tough, but it's important. I also notice some more wobble in your lines, like was mentioned earlier.

Your rotated boxes page isn't bad. The furthest boxes don't rotate any more than the boxes next to them, which they should do. This is a tough exercise, so I can't hold this against you too much. That being said, I notice that the issue with crooked lines returns here. The center box's top and bottom lines aren't fully horizontal, which ends up affecting the boxes above and below it.

Organic perspective is your strongest box exercise here. I have no major criticisms to give with this one, though I would like to mention one thing: when two shapes overlap each other, it's good to use line weight on the areas that overlap to signify which form is in front and which one is behind. This helps with clarity and readability in your pages. Don't apply that line weight to the whole line; just apply it to the part of the line that depicts the piece of the form resting in front.
