love the treatment on this; excellent choice of colors. the razor sharp focus is really brought out by the background, which here enhances without distracting. you might have burned in the brighter part of the background up near the top, but it's not bad as is. great expression. this also would look good with more negative space up in the top left.
A bit much of a green cast. I know this is what you were aiming at but it seems a tad strong. Just going trough and looking again, I like the composition and the subject. The background bokeh looks good. I'll bump you up a bit.
This is absolutely perfect. the look on the face is really cool - plus great image for this challenge theme - plus, love the monochromatic tones - contrast - everything is pitch perfect. I hope you win the blue ribbon - 10
