Hey, heres some feedback!

Lines:

Your superimposed lines have some fraying on both ends of them. Plan every stroke you do beforehand and place the pen down exactly where you want it before committing to the line. Some lines have slight arches and wobbles to them. Don't forget about drawing every line with your shoulder and performing them with a quick and confident motion. Try to lock your wrist and elbow movement before drawing, this helps me a lot.

Ellipses:

You didn't repeat most of your ellipses in the tables of ellipses exercise. You should draw every ellipse 2-3 times in one confident motion. Prioritise smoothness over accuracy. Try to approach ellipses with more confidence in your stroke. Don't forget about your shoulder!

Boxes:

Your line extensions/corrections on the rough perspective looks incomplete. It looks like you skipped them for some boxes or didn't extend them far enough. Also don't forget about keeping your width lines parallel to the horizon and the height lines perpendicular to it. Your lines for the plotted perspective look like you did them freehand. This whole exercise should be done with a ruler. Read the lesson instructions more carefully and don't forget to watch the video and read the text.

Your hatching on the boxes look messy. Take your time and really think about every line you do and perform them with confidence.
