Hi, congratulations for finishing lesson 1!!

Here are my thoughts:

Lines

Overall, your lines are very smooth and confident, especially on the ghosted lines and ghosted planes exercises. The longer lines are quite wobbly in the superimposed lines, make sure you are drawing from your shoulder and not hesitating when carrying through the stroke.

Ellipses

Your ellipses are also drawn with confidence.

Make sure you are drawing through your ellipses 2-3 times. You haven't done this in some of the exercises such as the table of ellipses. Drawing through them helps you to build up muscle memory in your arm so the shape comes out more even and smooth.

Your ellipses in the table of ellipses are nicely touching each other and the table without a lot of overlap, good job.

Boxes

Boxes are drawn with smooth and straight lines.

In the rough perspective exercise, the width lines should be drawn parallel to the horizon and height lines perpendicular to the horizon. The width lines on the back face of some of your boxes are sloping downwards: https://imgur.com/a/pT3c8J1

For the rotated boxes exercise, I don't think your boxes are actually rotating that much, hence the overall square shape. Please refer to this for what I mean:

I would recommend watching the video on this exercise once or twice if you haven't done so as it helped me a lot with understanding.

Good attempt at the rotated boxes exercise, you could make more of the boxes overlap next time.

Overall, I would say well done. Your lines are already very smooth and straight! Don't worry too much about the issues in the rough perspective and rotated boxes, you will gain a greater understanding of perspective after the 250 boxes challenge which will really improve your understanding of how boxes exist in 3D space.
