Ok, I gotcha. That’s potentially stringhopping. Or not. Can you go fast? Does it feel smooth when you do? If so, I wouldn’t worry about it. Lots of players use what looks a curved picking motion at slower speeds, but transition to a more linear one when they’re going fast. Andy Wood is a good example of this. If that’s what happens in your case, then that’s fine.
But if you experience a speed limit, and that limit is low, like under 150bpm sixteenth notes, then this could be a problem.
No matter what, your first step in picking technique is to find a motion — any motion — that goes fast and is at least reasonably fluid. It doesn’t matter if that’s elbow, forear, wrist, whatever. You have to find one motion to start with otherwise you can’t really play smoothly.
