I can't help but feel that this score is ridiculous, really a 5.4? This is a truly outstanding portrait, clear sepia tone, great tonal range, tack sharp focus right on the face and just enough blur in the image to keep the fun and energy going. The more I look at it the more i like it. Would have been a 9 or 10 from me.
Quite frankly I'm a bit staggered this didn't score significantly higher. It's clearly shot with an overall sepia tone so I fail to understand why you've been voted down. Some people are just really rigid with the challenge I guess, but it's a beautifully taken, fun shot that you should be proud of.
Okay...I'm sure some people are voting you down for this, but i'm not. It looks as if you didn't add any color, but you didn't do any changes (color-wise) in post processing either. You took a great shot of a sepia toned boy. I like it, i think it's great thinking outside the box...and it fits the challenge descritpion (well except the overall sepia tone part, but i'm ignoring that part.)
