Well...
...this sounds decent enough, but it´s very simple, and just because a song "sounds" simple, it doesn´t have to be that. This son however, reaaally sound simple all the way through, wich in this case is a bad thing.
Don´t get me wrong, i think it´s a decent loop... so why make it so long?
As for the samples you´ve used, it´s difficult to tell if you´ve even processed them yourself, as far as I know this may be all pure samples, wich really isn´t that difficult to mix together, now is it?
Anyway, like mentioned it does sond pretty cool, but very very empty. Even though there seem to be good reverb on the stings (your doing or pure smpled, i dunno), but the delayed guitar sounds really really cheap.
The bassy hit that runs through is pretty cool, but a suggestion to you is to try to keep the sounds that are loudest in the lower freq. mono, there are many reasons for this; if record played off of vinyl, it may skip if bass is panned/stereo widened, bass freq. contains alot of enery, this mean you basicly unbalance the whole mix when doing this.
Anyway, cool beat, and good luck with future project. I hope this is helping you out some.
