The breath you give to a spacey track like this is really nice. When I started listening to this, I actually honestly felt like I was in a spacecraft of some sort.
Not sure about the percussion; I feel it's too hard and too dry for something like this. Something a little wetter, more subtle and more awe-inspiring perhaps?
That piano is really well done. Light on the fingers, just delicate and nice for this song. The amount of buildup you give with four chords is pretty good. Only suggestion I have with that piano is to make it a little more 'distant' in the mix, if you will. Something that gives the impression that "whoa, I'm travelling through space, and this is huge." And then bring it forward like you do. Playing around with effects like these is something that I suppose can be done.
Thanks for the positive feedback I appreciate it.
You're right about the whole theme thing. I the song is smooth than so must be the drums so I'll definitely look into that. Same for the piano.
Thanks again for the feedback! :D
