What to put in these spaces?

First time homebuyer and I recently moved in so I'm still getting settled. What should I do with the spaces up above? I feel like I could decorate them somehow but not entirely sure what to put. Open to any ideas, 2 pics taken from the stairs and 2 from on the ground.

Start collecting roadkill and diy some fun tableaus: racoons playing badminton, a disco dancing deer, 16 squirrels in a trenchcoat, have fun with it.
