Thank you for the feedback!

I assume you're talking about the "shadow" on the side of every left wall. I honestly had no idea what I was actually going for here and that really shows(I mean wtf is that wooden "bridge").

Next time I'll definetly take some more time thinking about the whole scene composition beforehand haha

Very nice.

There are some lighting issues though. I'd consider clarifying what the darker section on the left of your platforms mean.
