I actually like it, that's pretty good in general...
Lines are pretty straight (maybe a couple are a little arching?) and the ellipses are quite good.
The only fault I can find is in the rotating boxes... I think that the boxes in the for perpendicular directions have their bases a little too long and a too drastic narrowing...
In fact the adjacent ones have maybe not enough space...
But it's generally good and I can see you got the idea... The hatching would have helped to make more easy to distinguish the boxes...
Next Steps:
I would not force you to re-do the exercise, unless you have the patience and the will, just to see if it can "turn up" better.
Said that you can move on to the box challenge...
