It's okay. One thing I don't really like is near the end the bottom notes are hitting some odd notes... Makes it a little too discordant. And maybe you could have some chords in there instead of the same thing over, and over, and over, then with some different notes thrown in...
Try to put some depth to the music is what I'm trying to say.
None.
I agree. The right hand part is good, but the left should be playing chords (and watching the key signature).
None.
