I checked your work and these are the things that noticed

Lines

Your lines are definitely wobbling here. I'm trying something that's working so far. Remember to speed up your arm trajectory a bit more just not so fast that you lose control completely. The next thing to do is focus your eyes on the end point after placing your pen on the start point. Lastly, just go for it. It's going to feel weird, I know, but your lines should straighten more. Another thing that helps is not to overthink it. Your subconscious naturally wants to straighten the line but that ironically ends up wobbling it in the end. How accurately your lines hit the end point depends on how good your hand eye coordination is which takes practice to develop that muscle memory so don't worry about accuracy for now. You strive for it but don't make it a priority. On the ghosted planes, you didn't plot points for some of the + lines. Remember to do that so your lines hit the center point with more planning to it and not have to guess. You can replot them if it doesn't look right but once you draw the line, that's it.

Ellipses

Your ellipses don't wobble, that's good. You're on the right track there. Only thing I couod say is that some are misshapen and some overlap. You probably need more practice to get a better shape out of them without wobbling the ellipses. I struggle with them myself so I can't give you better advice, sorry. On the funnels exercise, your ellipses don't properly allign to the minor axis. Be careful with that.

Boxes

On the rough perspective exercise, some of the back faces look off. Those faces should always have a side that's parallel to the horizon line and another side that's perpendicular to it because they're in one point perspective. Remember to replot points if it doesn't look right. On the rotated boxes exercise, you're making one of the mistakes mentioned in the rotated boxes section. The two boxes besides the center box both share the same VP outwards and don't rotate as a result. On the organic perspective, the edges of the boxes are too parallel to each other. No real convergence is happening and a few are are even converging the wrong way. The boxes need to have proper convergence to their VPs to show depth to them, especially those closer to the viewer. Also make sure to draw through the overlapping boxes. On those, you want to superimpose the silhouettes to clarify which boxes are in front, givibg more line weight to the closer boxes and less on those farther away.

It would be a good idea to do the superimposed lines exercise as well as the table if ellipses as a daily 10-15 minute warmup. Alot of the challenge from the last two exercises are covered in the 250 box challenge. You can superimpose those boxes to get even more good practice.
