Not bad for a sample.
Little more bass on the bass line would be good though, also try and tune the bass some.
Also, something more with the hook would do instead of just tremelo strings. Would of gave it panned strings and such to keep it at a more lurking dark mood or dark bells that hit and then explode n the reverb seperates.
Not much to say else, havent heard the rest of it, but, pretty nice beat. Keep it up.
