Very pretty but a problem here lies. It reminds me of clouds, undoubtedly, and the orchestration as I can get beneath the somewhat out of place bass drum is the majesty of sky. What I find lacking is that it is really a lot going on, but nothing in particular as far as a melody goes. The strings are pretty, and it really had me from 2:20 onward, and the little trills in the flute were good; so much so that I would've turned up the volume to hear them.
The bass drum, as already mentioned, is just really sharp so that it distracts me. What I like in the percussion, however is the cymbal crashes, and of course the rhythm itself that the snare and bass drum snare.
So really, beautiful stuff, but the lack of familiarity in melody with the sharp bass drum were all that is worth fixing for it to be truly great.
