This is a fan art for a fan boy. Lil Jackson is 10 years old and he's a big fan of Ben10. He requested a portrait of him in the alien Way Big form. So, this is what I came up with.
I was experimenting with the style. I wanted a flat chiroscuro with distinct linework between light and dark at first. That's why I left the lines on the face on purpose. But I ended up going for rather realistic rendering than the comicbook-ish look I initially intended to go for.
