You captured a certain innocence here. Nice job. The choice of background makes the dress seem to blend in. This reminds me of an old photo. Not sure if you were looking for that or not.
Certainly is a princess, this is a charming portraint. - A little too bright around the top of the head - the light encroaches into her hair a little, but otherwise a very nice image.
what a doll! i'm sure this image has brought smiles to many, many people. most excellent portraiture. you really captured her personality. i hope this doesn't get lost in the shuffle, and that it gets the attention it deserves. good luck in the challenge!
