I didn't feel it...
...and by that, I meant I didn't feel like I was up in the clouds.
If you were trying to go for that "adventure up in the skies" feel, keep the drums, add a bass line that runs along with the drums, and keep the high-pitch instruments thin.
If you were trying the "floating" feeling, remove the drums, use cymbals only (light taps only; heavy crashes give the feeling of disorder), and play with panning and, again, keep the high-pitch instruments thin.
Hope this helped. ^_^
