Yes the composition itself is cool and had it been played by actual musicians it would be sweet. A problem for me is that the synths or plugins you are using sound very MIDI, like in shitty old PC games or so. Perhaps you could some more organic sounding plugins using physical modelling instead of sampling? For example "Sculpture" in Logic, or Some of the synths in Reaktor if you're using cubase (though Reaktor was quite buggy for me).
I don't know, those are the two I have used and like. I'm sure there are other options. Then you can automate these to give the piece some more dynamics so it doesn't sound so stiff.
In the second track I also thought maybe a really low D note could be added at some points as a drone bass note kind of thing, giving everything else a kind of dark context on top of it? Well up to you.
