Perhaps a little unsharp (the silhouet), but I don't think that's any problem for this photo. It gives movement to the subject. Perhaps a (very) little crop from the right and (some more) from the left, but I'm not really sure.
Mark, this is a beautiful photo. I love the reflections from the floor. I'm torn between liking the dark tones and wishing there were just a little bit of detail - especially in the skin tones.
the only thing that bothers me in this picture is the crooked blinds. it looks like you have a beautifull stylish home, and they just seem out of place. great work with the backlighting.
what a way to start the challenge. this is purely fantastic!!!!! totally photojournalistic with a studio-type flare to it... if that makes sense?! anyways, awesome work!!!
