Seriously...try Black and White....much classier than colour..especially for non experts...kinda gets rid of many common flaws, that are highlighted in colour...and yes...possibly a different choice of model for that style of image...your trying to sell it, remember!!!
What in the name of Christ is this one about!!?
Before...
After...
I actually rather like High Contrast images...burns out the back ground...unfourtunately also parts of the model too...tho, that could be fixed with some dodging and burning...
