Replacing with my head would be a travesty to the bride. Replacing the groom's head with jeremy would also be a travesty for the bride.
Here's a what-not-to-do. From this terrible copy, I'd suggest not sharpening the veil. No more time to play, but I'll enjoy seeing what others do with it.
With your permission of course (IF not let me know and I'll take it down)
Heres my two minute edit:
Minor adjustments in LR2, then opened in CS3 and applied a texture and some minor sharpness.
I would clone out that bar (nice easy spot to do it with that wall), I would give it more contrast (maybe a heavy s curve in levels), and maybe hype up that light shinning at them while keeping its nice glow, and punch up the orange & red in the picture to give that wall pop (and it would probably pop that light a little too) and I would push up my bar on "clarity" a little in LR.
