Hey there mate!
Im Fred/Greatest artist on this platform. Art is a competitive sport in which only one will prevail, and spoiler alert, it's gonna be me! (Fr though ily, your art is actually crazy, I love it)
Just 3 cats and 4 rooms. They all have different gravity or something. It has its own gravity. I bet i can get some space logic to back this up somehow. I do not know who made the drawings on the sides but props to them.
