Post processing so far is being the death of me, Lisa, so I feel for you on that one, and won't add to what the people who know about such things have already said. I like the angles and the lines in this shot a lot, and the shadows add to that. Nice composition!
Nice perspective. I have to agree with the others that the color balance is off. Seems to be a bit too yellow. It works OK on the concrete and glass, but when something that you "know" the color of, like the sky, is off, it's really disconcerting.
Have you played with Selective Color yet? I find it gives alot of control to color adjustment. I agree with megatherian about the sky it is abit off, but I like the shadows and comp of the photo.
hi lisa .. i like your angle and perspective .....
i'd be tempted to saturate the green shade that's already in the glass, and maybe make the concrete etc a bit more orange as a contrast... but thats only my opinion and other ppl might think its better the way it is ...
