The character animation far surpasses the background and environment shown.
It does look SOTN-ish, but no offense you should redesign the environment to match the fluidity of the character.
You should go with a brighter and more colorful color palette for the environment, everything doesn't have to look so drab and cold. I get it's suppose to be in Hell but you can still brighten it up. Maybe you should use Dante's Inferno as inspiration for environment types.
