First off, the song is nice, the composition is thought through and it's overall a nice listeing experience. The synths and isntruments are well mixed and the melody is really calming and relaxing. I really like the voice lead.
Your singing is also good, although you need to work on keeping the long notes stable.
"I float among the clouds,
I play among the stars" <--- at this part you really had problems holding the high notes stable; there was much unwanted vibrato but with practice this can be solved. But you mostly hit the right notes and there were only 1 or 2 occasions where there was a little disonance but again: practice solves everything. Impressive voice btw.
I don't know if you have the resources, but it would also be nice to mix your singing better; maybe also some effects like reverb or a flanger. Would have given the song a new edge I think.
Overall a really nice song, was nice listening to it.
