Didereaux was rather kind in his comments; I'm going to be a little more direct. You're simply not there yet. You mention the photographers disease of "Wanting to show every image they have", unfortunately you have also caught, "I want to be a pro without learning the basics!", an all too common malady these days.
This body of work is simply not suitable for presentation to clients. The lighting ranges from unusual to poor, many of your cropping choices are (IMO) inappropriate, and basic, "technical" aspects such as colour correction & white balance are all over the map. You do have some very interesting concepts in your images, but the technical side is letting them down, significantly.
As a f'rinstance: You have four images of a real-esate agent. In the first, his pose isn't bad, but his chin needs to drop just a bit. The lighting however... you're blasting him from one side with what looks like a single, bare-tube, and the specularity on his skin is out of control. You've managed (whether by accident or design) to get a Rembrandt lighting pattern happening, but that's NOT what you want. In the second image, again, good, solid pose, but the same single side light and his near eye is a black hole and hte whites in his shirt are blown/nearl blown. The third image... this is an ideal real-estate agent shot. friendly, confident, but not cheesy. I wouldn't have gone with the lean, but that's a personal choice, but once again, strong side light and his eyes are pits. The last image has no business being in an estate-agents shoot. He looks like my father used to when Mom was explaining just what it was that I'd done before he got home...
Lighting for shots like these is really easy. A basic two light set, key light light 30 degrees camera right/left and with the centre of the brolly/SB at about the 7' level. Fill 1.5 stops below, on axis. Done. That will produce a good, solid, albeit not the most exciting headshot light.
I would recommend turning off your 'Open for Business' sign for a bit and spend some time really honing your lighting skills. The basics aren't hard, and a few weeks of concentrated work should get you to a much better place!
