You asked for feedback, so here it is:
- cool mix overall: style, structure, sounds — nice
- some vocal sync issues, mostly in the chorus
- a little short on mastering and final production, that’s a minor point
- you’ve chosen one of the most remixed acappellas in the site, and that gives a lack of originality feeling to the track

It’s all constructive criticism, of course. Keep your remixes coming!
