I think the composition itself is pretty neat and the repeating patterns with slight changes are quite nice. I think throwing in a low chord every once in awhile wouldn't hurt, but you might just be going for a very quick and light piece and not want to throw it off with that. But it's just a suggestion for an otherwise great start.
Thanks for the suggestion! I really am lost as far as how I want to finish this, but I will consider what you said. Many thanks!
