Paul, from looking at your blogspot galleries, you are far from the beginner photographer that I assumed in your first post, with a range from the very subtle to the vibrant, saturated images you seek for wedding photography - with commercial work and even a magazine cover - quite impressive! For me, a somewhat advanced amateur, the subtle is far more difficult, and what's easy is to push color channels to the point of clipping, or beyond for graphic, punchy images, preserving skin tones with masking, selection, etc..
Since you have all the software tools, and obviously know how to use them, I am confused by your apparent difficulties, as your own wedding portfolio samples show the whole range from subtle to vibrant also.
As suggested before, samples of your problem images similar to the other photog's samples would be helpful.
