Don't know about speeding it, but possibly add some variation in the hits, as you now have mostly one quarter hits most of them, the bass for instance. And that tends to get on ones nerves pretty quickly. Basically it gives the image of something like tok tok tok tok, like a headache. Not that this isn't good, I'm not saying that, but perhaps some little milder weapons, ie instruments, and try and make the melody go forward, because I had troubles in catching what it was like, mostly what I heard was notes after each other. Don't make that mistake, write a complete melody. You have a great start here, carry on
