I have plenty more where that came from, as I'm currently working on a little game project. Not sure where it'll lead me but it's giving me many ideas on things your pack could benifit from. Very great pack!
Just some more ideas while I'm thinking
-tractor, and harvester
-farmhouse
-silo
-bank
-Moneytruck
-swat vehicle
-aircraft hanger based on warehouse
-prop plane, and small private plane
-runway tiles
-city bus stop
-ruined/dead variant of flowers
Some ideas might be a bit out of the scope of what you're going for, but it can't hurt to suggest!
