Hello! I'm Sofia, I'll be giving critique for your homework

Section 1: Lines

Superimposed lines

I can see your lines were drawn confidently, I don't see any wobbling happening there so that's great! I can also see most of them don't fray on both sides but this doesn't seem to be the same for arching lines since I see some fraying on beginning point. Practicing ghosting method trying to reach both points will def help for this.

Ghosted lines

Same for above I see all of these were drawn confidently, also good to see there's barely any fraying on neither side, with some minor exceptions. Some of the lines I see don't touch neither dot, same as above, ghosting method can help with this. One of the lines, bottom to be exact looks to arc a bit. This is normal and can be worked on by continuing to practice these exercises and following proper technique. Make sure you're using your shoulder rather than elbow or wrist to draw these lines.

Ghosted planes

For this, I notice some of the lines drawn wobble a bit, be sure to draw these lines from shoulder and confidently. If you have a small desk or similar problem remember you can rotate your page to get the most of every line. Most of these lines also properly touch first and second dot o good job there as well!

Section 2: Ellipses

Table of ellipses

All of the ellipses are drawn twice properly so good job there too, some do go out of the margin while some others end line a little outside of their shape, but this is normal and something that can be improved with practice. Overall I'd say this exercise came out great!

Ellipses in planes

Same as above, all ellipses are drawn through and mostly touching all 4 edges of the plane. I notice some small wobbling in some of these and same as above some end go a bit outside shape a bit but overall they look good

Funnels

Most of the ellipses are touching sides of the funnel nicely as well as being kept in minor axis. Some, mainly ellipses on the very end of the funnel could be slightly bigger for them to touch all sides of the funnel.

Section 3: Boxes

Plotted perspective

This one was done nicely. There are some lines here and there which I notice are not parallel to the rest but as I mentioned before, this is normal and can be worked on as you progress and practice

Rough perspective

I notice some of the lines in this exercise wobble slightly more than previous exercises, so something to keep an eye for. Other than that, the exercise was done nicely and good to see perspective seems to be mostly accurate.

Rotated boxes

For this, I see most corners of the boxes are kept close and lines are done confidently. I notice squares (ones done with ruler) don't really match each other sizes. One in the middle doesn't seem to be in the middle where axis cross and ones on each axis are not same size, some of them going more towards a rectangle. https://drawabox.com/lesson/1/21/step3

As for boxes themselves, they look good but I notice some lines wobbling a bit. I see they are being rotated and lines being made from vanishing point. I see perspective is also done nicely. Boxes on the very far ends could use some work but do have in mind this exercise in particular is way harder.

I would suggest re-trying this exercise again. Mainly so you can work with proper helper squares. Maybe also taking another look at instructions for rotating boxes for perspective issues with corner boxes. Again, this exercise is way harder than others at this lesson but good to keep this in mind so it can help you in future lessons! - https://www.youtube.com/watch?v=gSbFHHrQK7w

Organic perspective

This one was done nicely. Once again lines are drawn confidently and boxes'perspective makes sense. I think for this my advice would be to maybe vary boxes sizes a bit as well as not being afraid to overlapping them since this will def help get a better sense of 3d space.

Conclusion

In general all of homework was done nicely. I would only suggest maybe giving another try to rotated boxes so you can try it with proper side planes. Once that's done I'd say you should be good to go for lesson 2. Good job!
