Nice oldskool groove man. I agree with others that it's a bit repetitive, chord progressions would work great with this, but instead of strings you should try stabs to stop the groove of your beat being slowed down by dragging strings.
Try changing up that bass, sometimes make it higher, or lower etc. Also make it a bit quieter. It's a bit too loud.
Everything else I can think of had been said
If you got the time, gimme some feedback on the track in the signature
