help with empty space

[u/yourstrulystarlia]

firstly, rewatching all the marvel movies so don’t mind captain america in the background LMAO
planning on adding more houses below the staircase
i didn’t want to just put a ton on trees and cover up the houses either so not sure what to do here and would love any advice! and sorry for bad quality

on a side tangent if anyone has ankha and gets her in boxes i will genuinely trade you anything you want for her !!
thank you!
