Help Me Make My Background Better?

[Gargamel]

Hey. I made this background a few days ago, but I’m not happy with it. The shading is my biggest weakness. Anyone want to take a crack at it?

Hi, your perspective of the room is completely broken.
I can help, write me and send me your materials in png

Personally, I would get rid of the bunk bed in the front and keep the other three in the back. The image’s perspective is confusing.
