Left is the "regular" image. Right is the same image (very roughly, may need some finetuning) edited with my "Hi-Pass tinted" Preset in Bibble 5. Personally I like the latter (right) one.
Which one would you use?
edit: well, guess the decision is made. The client (and model) has opted for the right one. No more doubts. Let's get working on the book.
