I think he has a bit of a posture issue in that his upper half leans back toward 2B more than I'd like to see.
I also think he reaches with the front foot a bit too much. I'd like to see him lead with the front hip a bit further into his stride.
I agree he looks smooth and smooth is generally good. But I think he lacks a bit of explosiveness and throws with a bit too much arm. I think he could build more momentum. I also think he might pull his glove a bit and that prevents him from keeping the shoulders closed a bit longer after the hips have rotated.
So, he looks pretty good but I think he has room for improvement.
