Evidently Steel's word if final. But I see 4 shades on other artist work here.
I don't think they are simple actually. I think it's the style, not the shades. Are these acceptable?
You know what? Talk to peyton. He probably knows more about what counts as a 'simple' pack than I do.
Also, it's not about the number of shades, it's how they are used. Patterning is fine. Something like a wayuki texture is not.
