ran out of ideas for a area of my map, need some suggestions (images included)

[Are you dead?]

a first map of mine named "koth_pastapit", i just need some suggestions for the areas around the side of the center building cuz i am drained out of all of my creative juices (a goblin drank it all). Just a small sidenote, red's spawnroom has a underground passageway, its the same for blu's spawnroom too. Just telling if needed
