Those synths at the beginning are a little wonky. They're not quite in tune with each other.
As to the mix, the big thing that I'm noticing is that the drum pattern is very energetic and danceable, but it's kind of buried in the mix.
Overall, things are kind of cluttered. I can make out pretty much everything that's going on, but they're not fitting together naturally; they're stepping all over each other.
I'd recommend going back to the start of the mix and getting your backbone right: Make sure that your drums and bass part are solid and working together nicely; then start layering in those leads. If something starts interfering with anything else prior, tighten up it's EQ or turn it down, and get it not breaking anything.
