Thanks for posting! Two issues: picking motion and hand synchronization.
I’m not getting a clear sense from this clip which picking motion you are trying to use. It appears to change, or at least move around in unexpected ways, and that tells me that it may not be completely smooth. It might help to take another look at what motions are available, demo them all, and make sure there is at least one movement you can make smoothly and consistently, at a wide range of speeds, on a single string to start with. Here’s our best intro to that:

Most 2nps players are wrist or wrist with a little forearm. I think of both as mainly wrist. Andy Wood is a great example of a wrist player with a very simple picking motion that works well for 2nps lines and is relatively easy to learn. It’s an upward pickslanting movement, so he starts those phrases on an upstroke:

The movement Andy is using here is the “Two O’Clock” movement we discuss in our recent crosspicking lesson:

I have no problem with the blended movements that players use when they mix and match little bits of arm, wrist, forearm, fingers, and so on, in a way they’re not totally conscious of. But only if it works. If it doesn’t, then I recommend choosing one of the simpler movements without multiple ingredients and seeing if you can get that to happen smoothly and consistently without unpredictable changes at different speeds.
The second thing that is missing here is hand synchronization. The picking hand and fretting hand are not really locked up tightly. That’s usually something I address again on a single string, with repeating phrases in a single position. Here’s one take on that:

Nice magnet-style angle in your filming there. Try to keep the picking hand out of direct sunlight otherwise it gets so bright that everything else in the shot goes pitch black to compensate. A window that gets only reflected light will light up the whole frame much more evenly. And I’d also rotate the camera 90 degrees so you can see your arm and hand together. Those two quick changes will give you a much better idea what’s going on in the shot.
