Hiya! I’ll be looking through this~

Starting off, your superimposed lines look good. There’s a tiny bit of fraying on the left, so see if you can take an extra half a second to line up your pen, next time. The ghosted lines/planes, look good, too, but I do have some recommendations. Firstly, try to maintain a consistent speed, rather than decreasing it as your approach your end point- it causes your line to wobble. Secondly, and as a follow up to this, if your line happens to stop short, because you were more concerned with confidence, than accuracy (as you should be!), don’t extend it. Don’t correct an incorrect line in any manner, actually. Just leave it as-is. It’s okay. Finally, as an extension to this, don’t cross things out.

Moving on, your ellipses look good. In general, I’d be a little more attentive to their roundness, and try not to flick my pen at the end of the 2 rotations. It’s causing your to run off-course. Instead, see if you can lift it off the page. Moving on to specifics, in the table of ellipses exercise, be careful that there’s no floating ellipses. Every ellipse needs to touch all available sides of the frame, including other ellipses, rather than float arbitrarily. The following 2 exercises look good, but it feels like you got a little too caught up in the big picture, and your confidence suffered. Try not to forget that, regardless of all of the added instructions, you’re doing the exact same thing in all 3 exercises. If your ellipses can look good in the ellipses in planes exercise, they can look good in the other ones, too. As for the added instructions, take care of them during the ghosting phase.

Finally, the box section looks good, too, but there are a bunch of things that stand out to me. The most obvious one is the sloppy hatching. The purpose of the hatching is to clean up your exercise, and make it easier to look at, and understand. Sloppy hatching does the opposite. Either take your time with it, or don’t do it at all. Next, is the automatic reinforcing. I mentioned this earlier, but it’s important, so I’ll mention it again: don’t correct an incorrect line. On a technical level, the exercises look good. There’s some minor issues, like the back faces of the boxes in the rotated boxes exercise not rotating as much as they should, and diverging boxes in the organic perspective exercise, but the 250 Box Challenge will take care of those, and more.

Speaking of, feel free to move on to it. Consider this lesson complete.
