>>1481558The easiest way to create these, is to find an image you lie and either vectorize it, or use a color tool in any paint image.
For example: what I did to make that, is the background was mostly white. Her suit is white, so ANTHING that wasn't white on Rei herself (her lips, her hair, the zipper, etc. that you see there_ I kept. Everything ELSE was made white - the background, the lines the shadows for the white stuff and the text.
I then didnt' like all-white backgrounds, so I made two versions: one with the baby blue color you see, and one of a flat gray.
So if I were to make one for Asuka, for example: I'd make everything red, except the orange of her suit, black, and orange of her hair (and if it were her with bandages, those, too) and then Iwould either convert it to another color liek blue (for contrast) or a darker red.
The easier way to do this, would be to learn how to vector, and follow the vector tutorials posted in the OP. t hen you can isolate the image better AND make it infinitely scalable.
