Nice but could do with some variation
I like the way this is composed, has a nice vibe to it. The problem is that it's suffering a bit in the way that Jazz-Funk does in that although sounding and feeling good, it takes a while to get to the point and does a lot of repetition. And man that's cool, repetition is good and all but once you've established the groove it needs to go somewhere and that's the problem with this; it doesn't.
The opening is promising, comes in with a twiddly little synth pattern, an nice deep bass line and then the drums hit the groove. Nice. Problem is it doesn't develop much beyond that. No new ideas come to the table and it just stays the same for four minutes when I was really hoping for some variation.
All this said you may have just wanted this to be used in a flash or to be remixed somehow and in that sense it achieves it well as it isn't in anyway obtrusive. Also singing your praises, it's well produced and ultimately has a nice feel too it. Drums are nice and punchy like they should be.
Overall good job but I'd like to hear some more variation.
