Hello! Sorry this comes in so late. Quite a few critiques, so they take a while to roll around. Nevertheless, here's mine.

I will say as an overall note that I think you've done a fine job in general with regards to your work. Good line quality, and a general understanding of the lesson objectives. Well done!

On your lines, I can only offer my kudos to you. I see nothing but confidence and straight lines, and with the bonus of pretty good accuracy. There is a teeny bit of arcing here and there, but that aside, you've done excellently.

The main thing I'd like to note on your ellipses is that they're quite confident. And, to boot, they're pretty well-shapen. The only thing I have an issue with would be a little bit of accuracy issues, but that can be fixed with time. In addition, your funnels are very well aligned, so great work there!

Your boxes are, too, pretty good. I do see some sacrificing of confidence in your boxes, so do watch out for that. This is especially the case for the rotated boxes. I see that the bottom left corner is a little messed up, but you seemed to have corrected that for the remaining corners, so good on you there. Also, in your organic perspective, the push for a bigger box doesn't seem to be very significant. Mind you, its still present, but a little less than ideal. Also do take note that you can use line weight to better clarify overlaps between the boxes.
