I agree with the drums. Dude, you're way younger than me and played it great so props there, but I'd always work with a drum machine/metronome for final cuts. I feel people can go with the beat better. I played the first four years of my bass playing back when I was young w/o a metronome.... I feel it pushed me back later in playing. I'm not saying that's you at all, I'm just try to say, no matter what, always play on beat.
I wish I could word this better.
