I have to say I enjoy doing illustrations that contrast different body sizes and styles. Big beefy guys mixed in with cute punky girls is a great case in point. One of the things I really like about comic book art is how you can play with this type of thing and explore that contrast. And after drawing kids for so long for my graphic novel Stargazer, it's nice to change things up and draw different body types.
You can see a few more illustrations featuring these characters right here.
