I really like the sound-track dynamic feel to this song. I especially liked those laughing voice samples, which really add to the mood. I suggest that the main spoken word sample, in the context of this rich and fun mix, might have benefitted from some additional treatment, to fit it in with the excitement of the music.
As I sit here, one idea that comes to my mind would be to pitch-shift the voice up into a higher but not un-natural register and then to EQ it a bit so that it is crisper—maybe even speed it up a bit to fit your uptempo fun.

I must admit, though, that I like the song so well I’d really rather you marry it with another vocal, or with samples which aim it for an instrumental. It’s just got a good feel to it.
