I'd say the problem is that her dress looks nearly as blue as his shirt. I interpreted that to mean his shirt was white and you just had a blue-cast fill light. You might just do a curves layer in PS where you drop the blue level and mask that over the flesh and her dress (and possibly her hair, though you seem to have jacked up the yellow saturation on that so high you might not need to tweak the blue there). Something to distinguish the dress, hair piece, and gloves from his shirt a bit more.
