Get close up and personal. Play with every aspect. The back lit image is the most interesting.
No telling what you can catch shooting through the glass.
If you are shooting digital, take all the pictures you can fit on card. Try every angle possible. Be creative. Try to see it differently from what the average viewer see. Make it a game.
Now go home, download the images to your computer, recharge your battery and return at a different part of the day. Repeat the above advice above.
Download and inspect all your images. Separate the good and bad. Work with the good in your photo editor.
If you have something you like, good for you.
Remember, work with a copy. You may want to revisit earlier photos to apply what you have learned since. Have a system for keeping track of your work. I put a "1" after images I have resized for the web. If I am making them for printing I put the image size in the name like "highbridge8X10.jpg."
Oh, and I would be remiss if I didn't suggest going black and white. It might work better that way. Might not. Sometimes color gets in the way. See how that reddish wall works if you change the image to black and white. It might change it from a distraction into a supporting role. Play with the contrast some to see what happens.
Have fun.
Changed mode to grayscale, then adjusted the curves, cropped and resized and applied resharp mask. Notice how the wall doesn't matter as much, and in someways more interesting. With color there was just too much information.
This could be a real fun subject. Go crazy.
