Hi I'll critique your homework.

Starting with the superimposed lines exercise I notice fraying at both ends of the lines, you should be aware of what might be causing this, it could be not using your whole arm or not drawing in a comfortable position etc, so keep practicing your lines.

Your ghosted lines are accurate but wobbly sometimes, so just like in the previous exercise keep practicing.

Your ghosted planes and ellipses are good.

Now in the tables of ellipses you want to delimit clearly the space your going to be using, this exercise is about the accuracy and confidence with which you can fit in the ellipses, so not having that parameter well established will undermine your work, this applies particularly to the second page of table of ellipse.

It's been a while since I completed this lesson but I remember that you only needed to do two pages of this exercise so be aware of that.

Now the funnels exercise, I see e same exact problem as the tables of ellipses, you can draw fewer and bigger ellipses, also there are some ellipses floating around, don't do this , you can practice it but not in your pages for your homework.

My recommendation for the organic perspective would be to make a more subtle use of line weight.

The rotated boxes exercise is good.

And finally the organic perspective is great you definitely pushed yourself in that one.
