My problem now is, I have to do my shoot tomorrow and I have no ideas. I`m going to browse some pictures online, but do you guys have any suggestions?

Think about textures. This will give you a good excuse to play with lighting too. Single textures can be interesting studies, contrasting textures can be more thought provoking sometimes.

For example, confine yourself to a small area, like a small exterior courtyard. Explore all the textures you can find in an afternoon. Watch the changing light bring out changing textures, etc.
