I like what I'm hearing.
First impressions: it seems like there's almost too much going on in the mid-high frequencies. It gives an airy feeling but it almost feels like it's too airy. Too much reverb maybe? For the most part I like the percussion work. Combined with what's going on in terms of composition, it all feels simple. It's not bad for a minute and a half, but it sounds like it's going to develop some point after it. Granted it's trance and it's more of a forced ambiance, but with how you started this piece it sounds like the theme (or themes) will get more complex. Something to keep in mind when you continue on.
Stepping back a little bit at the composition: Makes me want to think of Mirror's Edge. It's close but I feel like if you toned it down a little bit, it could quickly be applied to something in that game. It's hard to tell though with the pads and reverb up as loud as it sounds. Keep in mind this is my opinion, and I don't do much with trance but I'm letting you know what I hear.
Sounds sweet. I'd like to know when you finish this. It sounds like you're on the right track.
