In everyday life you don't get to look at someone holding a smile for this long - it's making me crack up. I think she might smack you if you maker hold that pose much longer. Good technique, I like the color, the light in her eyes, and the Depth of Field.

The lighting and composition are good. It doesn't fit the bill for me as a dramatic portrait though, but more good snap shot of a friend with a cheesy grin, sorry.

There really seems to be something special about this. Illusion or not I seem to get a real feel for the person behind the cheesy smile.
