That's great! :D
I looked over the asset packs, and these are some ideas I had:
Tools - garden hoe
Nature - rock/pile of rocks, stick/pile of sticks, weeds, boulder, leaf/leaves
Kitchen - bowl, cup, spoon, fork, knife
Bedroom - pillow (as its own object), perhaps different styles of pillows, hat, cardboard box
You have a very nice variety in the packs already, but some extra 'clutter' type objects would be awesome!
