Here is an illustrator illustration that was done for a friends wedding. They printed these head shots out and made pins out of them. For guests of the party to know who's friend you were. Lisa is a designer with Mission Pets Inc., they design and manufacture clothing for pets.
You can see my really rough sketch below the ink. I tend to be super sloppy penciling and get lost in areas that smudge. So I often use multi-colored pencils so I can see what I was attempting to accomplish.
While sketching Batman, I think to myself how square he should be. I often think of stealth technology as his costume, and how he represents his suit. Super tech, with stealth cape, and armor would make Batman look really cool in my opinion.
