There are 2 types of colour styles. Vector ones with sharp lines and idk what the other is called. but its like a regular painting with soft shadings and whatnot.
If anybody is interested. Ill be happy to send them the psd of both the colouring and the one with background
Btw. i just realise the issue with the eyes. i never made outlines on it. no wonder he looks a bit strange. ill try and edit it when im free
