Interesting. With the expression on the boy's face, I'd assume the guy in the window shouldn't be there? Or maybe I'm just making up my own story. Is there an angle where you could have gotten eyes in the first head too? This way seems a little strange.
This is awesome, but where's the 7th head? Is the photographer supposed to be the 7th head? You will probably get a lot of comments of a similar nature, asking for the 7th head.
Great concept. I like how you cropped this image, and your subject has a great face and expression. I also like the choice of black and white. It makes this picture sort of retro/ funhouse. Edgy and daring. Nice shot. You seem to be one head short, but what the heck...
There's one head missing... But I won't bother you with that, I'm sure others will. Very nice set-up. A bit too gray, not enough contrast. The focus is a little off but it works... well, not too bad! By the way, I recognise you and I take the opportunity to tell you I think you are doing very good for your age (or experience, I don't want to sound like an old geezer. Too bad about your DQ for the previous challenge, I tought it was great.
