Fooling around with a sort of old-school style test. It reminds me of brochures I would have seen at the school nurse's office back in the day. "Robbie feels happy because he has high self esteem."
Personally, I think Robbie looks happy because he's walking through the park on a wicked nice day.
I inked it all scribbly with an ultra fine point Sharpie and then colored it in PhotoShop. I've got a book Idea that might lend itself to a style more like this than my usual art style. I might have to do some tests with actual images from said book.
