Cool composition! Simple & quite effective for a relaxing song :)
Although I have to say that you need to work on your mixing techniques. As the reviewer below me (balancebirds) said, the synth at 00:35 comes in really loud. I think it becomes a little annoying to listen to, even when the sound and melody's are awsome.
Try to put more reverb on the synth and turn the volume down, it will become way more pleasant to listen to! :)
