Caroline won!

Reasons for choosing Caroline:
The dress fits the vibe of the picture
She is in realistic proportion with the background
I just love the bangs.

This is how I am thinking of laying out the front and back covers. The background image is going to wrap around the booklet to give is a cohesive aesthetic.

I will need to do a text print to see if the figure is big enough of if I need to make her even larger so that she will be a decent size when I get the final booklet.
