Jrob, hows it going?
What kinda post stuff are you going for here? Maybe I can offer some suggestions. As far as the photographs themselves go, the first of the three is your best bet. You've got this funky rule of thirds thing working for you in it. You've got a good deal of texture in the photos. Pay attention to texture. It's what's gonna make your photo pop after processing, (at least if that is in fact the end result your going for). All 3 photos have some exposure issues going on with them, but certainly nothing that can be corrected in PS. Even if they are in JPEG format, they're still easily salvageable.
