Dimensions - Ad Lib

Just created my first electronic style piece. Tried to create a more chilled atmosphere - would love to hear any thoughts/feedback :) 

NIce textural development. I like the futuristic + vintage feeling (because some instruments that remind rhodes). I think it would gain power with a contrasting section somewhere in the middle (different harmony / rhythm).

The mixing on the percussion around 0:35 is a little off. It's weirdly louder than everything else.
Relying on the C# as a common tone all the time is a little distracting, especially when it's an extension like in your B chord, I would move it around a little bit.
I agree with the comment on a contrasting section, but the great part is you have a lot of them, they're just not very fleshed out yet. Changes make the piece pop.
What's interesting about the chord progression is that a I seems to be eluded by use of the sus chord. It's a cool effect, but don't be afraid to take us there!
Nice work.
