Not bad at all
I like the overall feel of this song. The electric piano at the start in combination with those pads are just awesome. Good Job!
However, I think this song could use some more layers. What i'm really missing is the great big intense drop. This song really needs a big fat lead. The problem is that there isn't much happening. Only the same drum pattern the whole song. I know drum 'n bass has the same drums the whole song, but you can use some variation.
I would make the pads a bit louder. This also helps thickening (not sure if this is a word) the song out. And a second bass, which does all sorts of crazy stuff would help out too I think.
