>>19797932 (OP) General idea for it, although with not such a harsh colour choice. Wanting to keep the art used as close as possible to the original, although the colours could be more saturated and lively.
>>19797932 (OP) Here's the art to be used, probably from about the shoulders up like the above image and a similar shape. Maybe having the backgrounds behind them tie into their main colour or something to do with them?
>>19797932 (OP) And just a rough do-up of the idea here. I think the colours are a bit washed out, so increasing the saturation and such would greatly improve it already.
