Hmmm!! Don't know about exposed more like surprised, he does look like a bit of character that deserves to have an informal portarit taken.
Image wise the only "fault" I can see is that the flash looks a little overblown and the relative composition with the wall to the right does not isolate the subject enough against the dark background.
And he does have the, "BUSTED" look in his eyes, LOL! Nice shot, excellent colors but there has been something about this shot that just doesn't sit right, I can't put my finger on it, I've come back to it about 4 times so far and I"ll be back again to see if I can figure it out. Starting you with an 8 until I figure out what it is that doesn't quite sit right for me.
I don't see this as 'caught'..?? I guess if I had been there I would see it differently. The picture is not strong enough to relay your message and the title is having to do all the work. I'm sorry if I seem 100% negative on this photo....I'm not. The shot is in focus, it's clean. I just don't feel it's working for the challenge.
Cute. Didn't get it at first, but now that I see it, I like it. Hopefully there aren't too many people lacking knowledge in botony who won't see the relevance.
