Quote:

This is the EXACT aesthetic I've been experimenting with for years.



One thing is, what an artist tried to achieve, the other thing is what he gets offered by his efforts and good luck!

From the screens of your level: You already achieved a unique style! Look at the feedbacks. I don't remember anybody saying this or that is missing!
Your style is already complete!

My opinion, based on my experiences with my own game project through the last years, you have to make compromises to get a chance to come near a completing of the game. And the appearance of your levels is already fantastic, or, in other words, its not a bad compromise to keep them as they are - and concentrate on transition of the story to gameplay.

(Watching your project with big sympathy as always! )
