Five Close-ups of Ice (part 1)

[Wino]

Ice is my 6 year-old niece, and Ice is her nickname.
Recently she came to visit, and whilst she was playing I snapped off a few random close-ups of her face. None were posed for; I simply attracted her attention, clicked the shutter button and up popped these.
I know they're not technically the best pics in the world, but I do like the variety of natural expressions.
As an experiment I softened the first one. Too much, do you think? Also, I can't explain the difference in skin tone. Any ideas anyone?
