Thank You for your advice!Well done. One take, sweet. Not a critique, it sounds good.
Technique is something you can work on or not, you do you. Right hand picking excercise, two fingers alternate, then swap which finger you start with. Left hand excercise, one finger per fret, but it's only an excercise. Don't do it if you start cramping. Like what was said earlier, using your pinky is a good strengthening excercise. As is changing down from 4th finger (pinky) to third, which you did so well. I would have used the slack method of using 1st, 2nd and 3rd fingers. Less bird flippin action. lol
As a side, it seems like a good song, with fairly even bass notes, that you could try singing and playing your bass without the backing, and even use a metronome, to keep you in time.
Fingers of my left hand just don't want to cooperate with me sometimes haha. But I will definitely work on it.
