I added 2 layers (total of 3.)
One: background/sky. I increased the blues.
Two: Hope. I increased the blues, contrast and brightness.
3: Hope's bow and shirt straps. I increased the red. I made this a separate layer, because when you increase the reds on a person, the skin color turns funky. Funky in a bad way.
Now, I know this is some people's biggest pet peeve (um, Adam?!) Same picture, I just turned the first 2 layers black and white and left the red bow and straps. Deep breaths Adam, it's ok. I was just playing.
