Carl,
I totally sympathize what you are going thru. May I humbly suggest the following:
Having applied hand-painted highlights of various degrees as your second attempt shows you have done, leave the pink cheek works to a trust-worthy airbrush, allowing the ends of the afore-mentioned highlight strokes to be swallowed / absorbed / harmonized by the airbrushed colour. Then, just stating the obvious, do your various tricks to develop depth in the pink area to offset the unnatural discrepancy between hand painted front and airbrushed sides.
This method has survived me thru character-line-intensive face sculpts time and again.
Best of luck and will follow closely.
