Alright, this style is based on the Cute Sprays (at least that's what I think they're called) from Owerwatch. I really love this chibi-like style, so I just had to try it out with some the Ratchet and Clank characters, as well as Donna.

The art style I was inspired of, is by John Polidora (I believe he's name is!)
