part of my trade is photo retouching and every photo I look at I can see evidence of retouching. Generally there's a few things you do that is refresh the skin, give it a nice sheen, remove blemishes, remove stray or straggly hairs but to me she looks stunning and it would take a huge amount of retouching (let's talk plastic surgery proportions) to get her to such a stage as that you weren't happy.

She could have had an off day, wasn't feeling well, this "summer" weather will do that to anyone or maybe the makeup wasn't up to what you either expected or demand.
