If this was a quick run-through, then your work will be amazing when you've finished. Great rhythm, tone and phrasing.
I most definitely enjoyed this piece which btw I'd never heard before. From the music I get the feeling that something very intense is going on, and I want to feel more of that intensity...in sense of color and volume, dynamics and...?
Guess what I'm trying to say is I felt pulled in a musical direction, but then I never really arrived (?). Like I expected you to get louder here, more saturated there..in a nutshell...a teaser
or something......hmm hope this helps. I think you are on to something very exciting with this piece. Love to hear it again!
P.S. I don't think it needs to be any faster...enough activity at that tempo imo!
