Firstly, grats on clearing lesson 1! Good on you for pushing through to the end to get it done! And now for my crit.

Lines: In general, good work. A good majority of your lines are straight and confident. A couple of your lines are a little bit wobbly, but I'd attribute that to getting used to ghosting. In future warmups though, do try to create longer lines, as this would further test your ability to ghost confidently with your shoulder. That aside, good work here!

Ellipses: Again, wonderful job here. I can see the shape of the ellipse without much mishaping, and they're done mostly with great confidence. In your funnels, though, there are some ellipses that are a little tilted, and so not aligned to the minor axis. Try to watch out for that.

Boxes: They're fine. I'll note that in general, you can make several planning points before executing your lines. I recommend placing a point and ghosting a little, and in doing so, you can estimate if the line is correctly angled and/or of the correct size. This can potentially prevent the diagonals as in your rough perspective, as planning would generally allow you to iron out the obvious diagonals.

Your rotated boxes look not bad. Though you need to also consider that the bottom faces should also converge, so the bottom faces don't look too "flat".

Organic perspective is done pretty well. While box construction isn't perfect, you'll be able to iron that out soon in the upcoming challenge. In addition, you can use line weight in the future to clarify overlaps between the boxes.

Overall, I think you've done a pretty good job here. You've shown understanding of the main learning points of each exercise, and executed them with pretty good compentency. Give yourself a pat on the back, and prepare to work in the box mines for a while.
