Work more on base and beginning.
As far as Ice Cap remixes go, it starts off pretty much the same way a bunch of others do. It'd be cool if you made it more lively, less subdued, more interesting. I did like when the melody came in, and the harmonies on the guitar (that was a guitar, right?) go along well with it. The trills at the ends of phrases... I'm not sure if that really works.
Just suggestions, anyway. You mentioned it's a WIP, so I hope you don't mind.
