Well, doing things like army bases, battlefields, streets would be one option.

You can also diversify yourself.  When you decided to start doing scenes was there anything in particular you wanted to do?  Also try looking at what is available now and seeing if there is some kind of scenes that either aren't available or that you think you can do better than what's out there.

Here are some random ideas as well:
-Houses and rooms of different styles and periods
-the inside of an office building
-Neighborhood or city streets
-cafes, diners, and other places to eat at
-an indoor mall
-churches, temples, and cathedrals
-sci fi and fantasy sets
-nature scenes: cliffs, fields full of flowers or crops, deserts, beeches, jungles, mountain sides, caves, etc
-a prop pack with enough different pieces to be used with a variety of existing sets
-maybe something inspired by, but still original, from what you've seen in movies or TV... like a scifi conference room like the ones used in star trek and star wars or your version of king authur's round table.

WARK!
