A little more atmosphere, please?
I thought it was a great song, but personally I don't think the pads were "prevalent" enough to work with the piano and form a dream-like progression.
A little more work could have been done with the drums and clapping, making the drum roll sound a bit more subtle, kinda like the hi-hat roll you had going on at the end.
Overall, I just didn't think it met some of the requirements of a breath-taking dream trance song. I believe a few modifications could be made to make it sound more "dream-like" though.
