I think the left one nails it. I like the fact you've managed to get the feel of a bookish guy but by going down an alien, unfamiliar route.
the right one has a lil bit of the new dante.
Their clothes look like Native Americans outfits.. reminds me AC3. Very cool
cool! i really like all your charaters
The dark haired one makes me think of Elvis from the seventies. The costumes are certainly original without being contrived.
Man your characters always look so solid.
