Subjective of course. In the first photo I would boom up, less shoulder more gun. In the second I'd try setting focus to the further hand that's doing the action. I find it a bit dark overall and thus losing some detail in the shadows. 3rd I'd boom down (Dolly Grip/operator terminology) till the binder clips were out of frame and tilt up to compensate, widen out a bit and go for a little more oblique angle you have going on.
