Soundboy,
Cool intro, I won't ... LOL. This has a nice little groove to it, but the strings (I think they are strings) sound like they are way off key. The break you have with the laugh build up is real nice. The subbass line sounds like it is a little low in the mix, although I am listening in headphones.
The drum line after the change up doesn't sound right. It kind of leaves you hanging at the end of each bar. Here come those strings again, they really sound bad, I would get rid of them or do some repitching as they really only muddy up the track and confuse things. Now you have another string sample going on and this one is way off key as well and this one is way too loud in the mix.
Also your main line (played by the guitar) doesn't change up at all and gets monotonous after a while, try dropping it out or adding some change ups.
