Chevyt, looks great to me. I'm no professional but I'd say its well exposed, very natural looking, evenly lit, and looks to be a good natural smile. Well done
The last pic from cbayton is interesting. I didnt realize the k200 did so well. I don't know if I have my settings wrong but thats one thing I have trouble with on my k20d, its like the dark areas are too dark and then I end up having to manipulate it in LR to lift the shadows a bit in a high contrast scene like this. I guarantee you if I took the same pic you wouldnt be able to make out anything in the middle of the hallway in the last pic like you can with his k200.
