Hi, I think it's a really good and quite professional work. I especially liked the drums sample selection (actually where did you got them from?). Moreover, the whistle is quite cool and brings the mood to the beat and last - the cuts are cool (I am a fan of them to be honest). I only think that the drums could have hit harder (especially the kick), but I wouldn't personally be able to make it better that you did.
I would appreciate if you could check my tracks and let me know what do you think. Please refer to my signature for that.
