hmmmm
I'm sorry to be the first lowish grade on here :( I understand that you were setting a mood. Impressionistic music speializes in that, and that's what I consider myself leaning towards in my compositions, so here's my opinion.
The alberti base in the beginning set it up perfectly and had a lot of potential. The constant build up i thought wasnt as fulfilled as well as it couldve been at around :48, the added strings were nice, but why not elaborate on it? When using the alberti base, it's hard not to sound redundant, especially when using chords to exemplify a melody, i even have issues with that. I didn't think it worked too well in loop either. At :57, I wasn't sure where you were going with the ascension in the piano with the echo. In my opinion, it was monotonous. This would be a perfect intro to a longer piece though :) I suggest make a sequel in addition to this. You definately have something going here. Hopefully I didn't seem like a prick, if i did, sry :( Keep doin what you do dude.
