Two different versions of the same image. I’ve done one in “realistic” coloring, which works well I think.
The other one is done in black and white mostly, and I chose to keep the lips red and used purple for shadows. I think this gives the image more impact. Although I like the “realistic” colors as they work well with each other, I personally prefer the second one as it is a bit heavier in contrast, this accentuates her characteristics.
