Not bad.
I like the bass line, the drums are good as well.
It seems a little overly airy to me though. I know that was probably what you were going for, but it's a little overpowering.
I think what could make it a little better would be either to tone down the airiness of the high synths, or alter your drum beat to seem less heavy.
For instance, you have the open high-hat with a rock drum beat going on, but you have a trance-like main theme going on, and it's a strange mix.
Just my thoughts, hope it helps =)
