My honest feedback to your homework:

Lines:

They look slightly arched to me. https://drawabox.com/lesson/1/ghostedlines/arc

Your lines are smooth and without hesitation.

Ellipses:

Your ellipses are very cool, I just noticed a slight misalignment in the funnel exercise, but you made a mistake trying to get it right.

Boxes:

I noticed your difficulty in doing them freehand. Despite this, you did well applying the concepts learned so far (you will notice a big improvement during the 250 boxes challenge).

You did a great job. Proceed with the DAB, just don't forget to redo some of the exercises from this lesson as a warm-up before you start drawing (and be sure to apply the 50% rule to your routine).
