Well, my two cents:
- Normally, I don't play over the neck pickup as you do. Specially on faster songs, it's more difficult to have control over the strings because of the lower tension there. In your bass, I'd play not exactly over the bridge pickup, but
slightly towards the neck. Strings have higher tension there, so you're more in control because of the faster reaction to your attack.
- Something I always remark to my students and highly criticize from your performance: If you're going to show something to get opinions, you should wear your instrument
as you would when playing with your band. I mean, you didn't even hang your bass. How do you wear it? High? Low? Maybe that sounds as an unimportant detail, but it's more important than so many may think. That highly affects your playing. In fact, everybody should practice wearing the bass as normally does, or at least keep it at the same relative point when seated (that's one of the advantages of wearing the bass high).
- About your left hand: I think you need to get more into the concept of "economy of motion". When you try to use your pinky and middle finger for playing a fill, so many things happen there. You raise your pinky so high off the fretboard. The thumb, that supposedly should keep the same position, can be seen when you try to do something like that. Judging for your LH's (awkward) position when you play the G string, I think you have your thumb's fingertip too toward the bass side. Try to put it slightly behind the middle (slightly behind the "skunk stripe", if your bass has one). The fill I'm talking about is: You play E-E-E-E-E-E-E-E-E-E-E-E-(D-E-D-E?) I could never understand what were you trying to play in that part I put between parentheses (hope you understand what I'm talking about), because the aforementioned problem. Keep things the nearest possible to your fingers!
Of course, there are so many opinions about the proper technique on bass and all of them are valid. Louis Johnson puts his left thumb exactly the opposite way I told you, for instance. Being a so young instrument, the bass guitar's technique hasn't "settled" as the real old instruments'. The "big problem" is: I think it will never do. Hope this helps!
