uprising always jumps on everyone about overused samples. lol but he's got a point. :] i'd suggest playing with the synths til you figure out what sounds nice :]
These samples have been over used buy every one inside and outside audio tool
I like what you are trying to do here however as a Musician something has to be said for originality .. try digging deeper for the samples that you use m8 dont use the obvious ones of if you do c ut them up .. just a tip for you :) have fun m8 and keep it up !!
