Awesome!
Great samples!
I think the sub bass has a little too loud. Or the there is something that is creating a really deep sub =[
I love the drum samples (Hats are a little high freq, but that's ok)
I really like the synths and leads, they sound cool together.
Try bringing the sub bass lower, bring the main lead up, add more variety of synths under the same pattern so it has more power.
Everything is good! but too much sub bass, I think that is making the sound volume lower and throwing off the mastering.
