Sounds a bit redundant... learn how to replicate classical counterpoint and NOW you are creative.
I'm joking

Nice sounding piece, but I'd agree on the harmony part. There are some very expressive chords (either in classical music or in jazz) that can reflect a 'floating' or 'space' type feel. Keep working at it, you have some interesting ideas! The thin texture you kept is pretty cool, gives off a feeling of suspension or stillness.
