[sketch] ideal : vivid color oni (Patreon)

Using vivid color (blue/red/green) as skin color.
(This pic has pale color because just sketch, but I wanna use almost primary color.)

If I can draw them well, I assume they will be a very lewd characters, so I want to complete them to a good quality somehow. Maybe it wouldn't be a bad idea to change the shape of one of them🤔
