Hi, I'll try my best to give feedback!

I think you're drawing your lines correctly, they look pretty confident and there's no major flaws to them.

The ellipses you've drawn are confident and pretty accurate, in the tables of ellipsses they don't overlap with other ellipses but they do go out of bounds occasionally. If you draw more ellipses then you will probably get better at it over time, so I think you should try and incorporate some of the ellipses homeworks into your warmups.

Your boxes are also pretty good, I think the perspective of yoru boxes could use some work. Another thing that you should do is try to add thicker lineweight to some of your boxes, it'll make them appear more solid. Only add lineweight to the outer lines though.

Overall, I think you understood the lesson pretty well. I think you should move on to the 250 box challenge.
