Digital Self-Portrait Ideas

I think for my final Digital Imaging project I would like to do a self-portrait like the second one. I like how they have combined multiple pictures together and how they're all cartoonish. But I also really like the third one because It's got different areas different colors and textures. I would like to do something like this but do it in one color just blending it from light to dark. And using different textures. I like the first portrait because it's all completely cartooned and it's just one solid color with the outlines of the person, but, it's still got a lot of detail. I would like to do something with this except maybe like a comic? Or with dulled colors instead of just the one color.
