Yep, we're nitpicking, and yes, you're right to keep trying to perfect it. You will probably never get it perfect (very few will), but it's worth trying.
There's nothing wrong with a narrow stance per se, but the more narrow your stance, the more acute the angle of your shins to the floor will probably be (although this will be affected by other proportions too).
Having your shins more vertical will probably make it easier to pull the bar more vertically (although it looks like you've got a pretty good bar path in that latest vid, but it is a bit of a funny angle) and probably help with keeping your hips back and probably help with using more glutes to get the bar moving.
You just have to experiment a little to find your exact starting position. When I look at your setup, I just want to give you a shove in the face to push your hips back a few inches.
