If you want to explore more abstract reflection photography, try working in a big city where you can shoot into department store wndows with mannequins and other interesting displays and simultaneously see the reflections of buildings across the street behind you, and with people walking by on the sidewalk around you.
You will need to shoot on the north side of the street, or either the east or west streets as long as the sun is behind you.
Night shots can be even more interesting if you use a tripod and longer exposures (2-5 seconds at F/16) as you will get interesting streaks of colored light.
Oh gosh this is the first time I've seen what reflective photography is and I really dig it also. I think i may start practicing with this effect also.
