Hi, it's looking good! You seem to have a good understanding of what the exercises want you to accomplish. The major flaw here is your work done in pencil. It looks like you've allowed yourself to erase or draw over some lines multiple times.
Doing the exercises in ink would force you to be more deliberate with each of your lines and would ultimately improve their quality.
Your planes look great, but I think your ellipses and organic perspective slipped as a result of using a pencil.
Before proceeding I believe you should switch to a fineliner or ballpoint pen.
Next Steps:
Before moving to the 250 box challenge I recommend you complete an additional page of the ellipse table and an additional page of the organic perspective exercise.
Make sure to ghost your ellipses as well as the lines that make up your boxes. When doing the ellipses, aim to do only two passes around the ellipse.
Make sure to use ink to get the most out of your exercises.
