I think the loops is good.

I agree that it needs a little more percussion, but that doesn't mean that the drums or whatever you put in have to be apparent in the mix. I like the simplicity of the sound.

The congas are a little dry, imo, plus they sound a little too much like congas for me.

The rythym sound really straight. maybe some staggered stuff in there would throw it off a tad. These are just what I would like to hear...the loop is already good.

Oh, and if your looking for funky, I think you need a bassline that moves more...instead of just following the kick.

Hope this kind of critic is what you were looking for...
