When i was younger, i spent all my free time in a kung fu school... i would have KILLED (not literally ) for a photo like the Karate guy... though I would have asked if i could see more examples of what i want the graphics to look like. You've got a good idea here. I think, it might best fit by having the edited ones fit a related scheme to whatever the subjects has a passion for.
EG: if the first one (gal on car) had a passion for 50's cars, cha-ching $$$$!!
I recently completed a High School basketball team photoshoot. Each had just a basic pose, and one I "worked it up a little". Next thing you know, i'm getting emails, "can you put me on an NBA court with so and so..." another was, "can you [Use a strong radial blur] and make me look like i'm rushing past (another team mate)..." Sad to say, my photoshop skills are too basic to do what those guys were asking for, so I just sold them the rights to the file and told them to take it to someone who could.
I do understand our fellow poster's comments about the quality (of course some just cant see the value in at all), but despite that, you're a businessman... go make some money! Anyone mentioning the idea is not worth it (though i didnt see anyone go that far), i'd let experience differ with lack of experience, and just do your thing.
I like to see more of them eventually - just mention what the passion of the subject was. Hats off for the idea!
