Great playing! Thanks for posting. You’ve got some ferocious wrist speed happening. I can tell you what I see, but have you watched any of the Primer, and what picking motion or motions are you trying to make?
In general I think what you’re doing looks like a great start. A lot of people get hung up on doing the core motions, where they can’t go fast without bouncyness or tension. You’re way past that.
The lines you’re trying to play all require double escape or mixed escape motion. Most people even advanced players can’t just play an open string scale with wrist motion like you’re trying to do. It’s doable, but the motions are deceptively complicated. Hard to understand, easy to do. So you’ve taken a nice step here getting the single string speed thing happening, and then getting some of the scale stuff happening at an intuitive level.
To make this more conscious, have you tried playing any roll patterns? That’s another great way to work on these “wrist only” type approaches like you’re going for. Here’s our lesson on that:
This covers the two main approaches for doing this, the Andy style and the Molly Tuttle / David Grier style. You’re already using the Andy style. This video will explain how that works, as does the Primer “wrist motion” sections - especially the “wrist mechanics” videos.
In addition, most players that do the kinds of acoustic lines you’re doing here use a little more pick exposed in their grip. This way their fingers aren’t so close to the strings that they accidentally damp them and cut off the sound. That may be happening here. And you want a bigger motion so the pick strikes and moves past, again, not cutting off the sound when the pick strikes or rests on the string. That also may be happening here. That big, open sound with clear tone and attack is what those players go for.
The “open string scale” clip comes closet to this at points, but I think knowing more specifically what motion you’re trying to do, a la the crosspicking lesson if you haven’t seen it yet, and then doing the bigger pick / bigger motion thing can help get closer.
Otherwise I think you’re actually doing the core motions correctly, and this is a great start. A little more conscious feel of the motions you’re making, and some more variety like the roll patterns, could unlock some more clarity.
