It could have been longer, and looped better, and had percussion, but I still 5'd it. It's pretty, but it's still just a I-iii-V progression.

I think it's pretty, but I'm not sure I like the samples you used. Also, the way the notes cut off around :09 sort of disrupted the smoothness of this piece IMO. I like how you tried to create some dynamic contrast at :14, although you may have needed a crash or something to transition into that part. I like the melodies, and the progression isn't that bad, but I think you need some drums and more structuring in order to make this piece more interesting. Also, it doesn't really loop that well IMO. Sorry this is such a negative review, but I like these harmonies and I think you could've done a LOT more with this piece. For example, :46 seems like it should be a climax, so maybe you should add some more pads there and some drums and really turn it into a cinematic one! Little things like that can really bring out the emotion in pieces like this. I'd love to see this made into a full-length track with more structural variation. Keep at it, man! ;D
