Character thoughts

I started to explore quite simplistic ideas for characters, as I want the main focus of my book to be the setting/background. These ideas for a typical teenage boy are influenced by Jamie Hewlett's bleak but expressive and dark artwork for Gorillaz, I think the idea of blank eyes is really interesting as it conveys a sort of openness in the character and keeps it from looking like a specific reference to any one person in particular, as eyes are often a defining trait of a person. 

These ideas are more comical, I was exploring thoughts of an Indiana Jones type adventurer as the character here, for comic effect and exaggeration, having him cinematically navigate a very safe danger free British park. While I think there's potential for humour, the story I want to tell is a human story at its core, so I don't want the character to visually stray away from a realistic portrayal of a person into caricature.
