Hey, ken here. Incase anyone wondered what were my main inspirations for the environment designs, take a look at the following concept artists....
In particular Feng Zhu's TMNT environments which are striking yet use minimal colour palettes. Ryan Church's work is technically masterful due to the lighting he incorporates into his work. He is extremely adept at creating a 3D space on a 2D medium and bringing his work to life.
Awesomesauce :D !
