Take the sub down in the buildup. When the sub fades in the buildup and then kicks in with the drop, it with create a heavier feeling.
I agree with the others here, mixdown could be a bit better and the snare is ok, but not superb
And the use of the jungle breaks are a nice touch, but now those breaks have alot of high end, and when the 'normal' drum pattern kicks back in, there's too much of a difference, so maybe highcut the breaks a bit, see what that gives, or layer a break beneath the pattern, experiment a bit with that..
