Justin,
I've totally been there... a couple years ago I revisited some street work I had shot 15 years previous comprising some 600 images. I re-edited it into two entirely different bodies of work (15 images each) that I couldn't have envisioned when I Was a younger and different man. Interesting how our subconscious can allow us to create images that we may not even appreciate for years to come.
While I find most of the images you posted to be striking, I do feel a discordance between them. You are dealing with a few different issues. The images vary in scale, perspective and overall spatial feelings. If you want to create a cohesive body, tack all your images up on your walls and ask what the work is trying to tell you, and then find the images that speak that most clearly... I expect you will find them to be visually homogenous. The depth of images 1,3 & 6 provide an eeriness that for me clashes with the subject matter. I respond strongest to 2 & 4, as I find them graphically interesting, non-confrontational and clearly telling of the dilapidation of the site, which is I imagine what drew you there in the first place.
My .02.... maybe .03 cents...
