Hi Rodney and welcome. You have a varied portfolio there, if I see any one aspect which you could improve I'd have to say 'soften it a bit'. You move in close, which is good but a little unforgiving, and you tend to like both fairly contrasty 'dry' lighting conditions and a contrasty processing.
Try for example looking for reflected or diffused light for portraits, and using the Portrait preset (JPEG) or a similar process on the camera. I think you are aiming for contrast and impact, but that some of the subjects could work better with a more toned-down, lighter, more delicate look.
