Hello!
I like this overall! Here are some things I noticed--
Were you influenced by Debussy at all? I would bet--why else would you use three staves?

I personally don't like it, but I suppose it's fine. I actually think it would be more worthwhile to just move it to the middle staff.
Not that I don't like ostinatos, but I think you should have some chord changes in the ostinato. It will give a bit more variety. Either that, or add chords separately. No problem with NOT having any, but that's something I would do.
AAH! Please use staccatos at measure 34, or else I can't read it.
Measures 39 and 40 are too sterile, especially in an exciting piece like this. Try putting some sort of frilly little thing in there and see what you think. Also, don't limit yourself to starting the phrase on 1. It can be very artistic to start the measure before with a run or something.
I think your ending should be a little more exciting. The tempo changes mess with my head. This should really end on an exclamation point!
Overall, nice idea, but some things could be better.
I hope I have helped!
