hi!

I I will try my best to help you with som contructuve critique. First of all your ellipses look good, symmetrical and even. maybe not draw through them so many times, two, maybe three is enough. In many cases thy look drawn through at least four times. Also your ghosted planes look good.

you could practice your lines more. they look a bit curved and/or wobbley. I do ghosted lines and planes and ellipses for 10-15 minutes as a warm up before I do the homework. it has helped me a lot to get the lines straight. I dont know if you already do this but If you dont I recommend it.

In the rough perspective excercise you have drawn the red lines to the VP, instead you should draw them from the parallell lines of your boxes to see where they end up. I Recommend that you take another look at the examples and instructions for this excercise.

dont worry about the rotaded boxes excercise, I can see that you have understood the excercice.
