Hello BWXD! Today I'll be doing my best giving my critique and hopefully this proves useful to you.

First of all are you using the 0.5 fineliner? It seems to me you are using some kind of ballpoint or just not a very good pen in general. It's okay to use a ballpoint for now, but I really recommend upgrading if you could (especially for higher lessons)

Here are links regarding about that matter; https://drawabox.com/article/ink , https://drawabox.com/lesson/0/5

Consider to invest in fineliner pens, though smudgy pen isn't frowned upon or not allowed - it will definitely improve morale and the cleanliness of your work.

So I will critique as sections of Lines, Ellipses, and Boxes

Lines

Your lines are quite wobbly, I can only take this implication that you are not confident in drawing your lines. Don't fuss to much over accuracy and try doing very confident linework (as it's very important in the earlier lessons), because the next lessons will be very elaborate and sophisticated homeworks that it's very beneficial if you are used to drawing confident lines already. Since Lines encompasses a lot of things in what we draw including ellipses and boxes, it's crucial to have a good footing on it.

And also you have quite few arching lines, try to fix this by arching your lines in the opposite way of your tendency to arch.

Overall it serves the homework.

Ellipses

Your Ellipses are surprisingly not bad, it's solid and neat but could definitely have more room for improvement. Ellipses in Tables need to be really enclosed in the bounding boxes, try to be more mindful about it since it's important for later lessons. Just like with your Lines, Ellipses needed to be drawn confidently and as for my critique it's the same application for lines since it's a parallel problem. You did good on drawing your Ellipses 2-3 times average, try to unify those uncertain lines into a whole clear Ellipses, try narrow that gap and you are good to go.

Ellipses in Tunnels are the most neat out of them all. One tip to add is to have the minor axis slice the Ellipses in 2 symmetrical halves, it seems that you already attempted that but it's always good to keep in mind/remind. Keep up the work!

Boxes

Boxes suffer the same with the lines since it is just a compilation of lines orchestrated in a perspective manner. Though your boxes does align with the homework needs. Overall I think you did everything right, it's just the lines are supressing the overall structure of these lessons.
