There is an image of her on your website that I believe would have a better chance of not only entering but winning something. It is the white on white profile of her. It is a bit more art like. The image you have presented here is great for the owner (LOL - you ) which is probably why you like it.

This show want to sell or they would not take a commission from sold images. Just somewhat what your competittion is where you are entering a division of portraits. As a PPA judge I would critique this portrait differently. Thinking like the judge for this show is trying to understand where they are coming from. The art world of judging is different than people judging strickly photography.

Good luck - hope you win!!
