I like the feel of the piece, especially once it hits that strings breakdown, then its really grooving, but the main section sounds really cluttered. You've got a really busy kick, bassline, all of these scratching sfx sounds, sax/key leads, etc.. In contrast the string section has a really strong groove to it, I can't help but bob my head when it gets to that. Some general things you can do to improve this remix:
1. Tone down the main section, find a consistent groove that all of your rhythm section can sit in and let only elements you want to really emphasize go nuts.
2. Doing some basic EQing/levels on all of these tracks will help the mix gel better.
3. Consider low-passing the bass. Like Monobrow suggested, hit that range where it gives your bass some funk.
