This is how a made larger-via-PS version of the photo could possibly work as a poster, I mailed it like this (and without letters) to the dance school but haven't heard anything back about it. In this photo also the black girl's shoes were made black (they are originally white), and her skirt originally is a bright, shiny turquoise blue ... but since she is the not nice of the two sisters, and the greedy one, who does no good deeds and is not rewarded with gold but tar, her skirt just had to be black! So ... it is black now ;).
