For your first song, this is really good. I like how you blended two genres as smoothly as you did. I have a few remarks though:
- Do you have a sub bass going? I feel like there's something missing in the bass range when the dubstep basses aren't blasting.
- And they are blasting. I would turn down your dubstep basses just a little.
- At 2:58, the hats playing are too loud.

So good job overall. Make sure you practice your composing and arrangement, and the rest will follow.
