Ok.. I couldn't help myself... here's my shot:
The thing is.. these are all very good. I took a slightly different approach to mine.. of course, corrected that color cast from the camera but I don't typically convert to B&W when I'm going to do selective colorizing.. I usually just use a slight desat which still gives you that color look (you don't lose the color of the cheeks, ear, eyes) completely.. but enough to really bring out the color areas.
Done via Photoshop CS3, a bunch of layers, Screen mode blends and a few DFX filters.. and some sharpening which the original lacked.
Enjoy!
