I have a question: Did you do anything special to match color temps between flash and the practical lights inside? I've tried this type of shot and gotten horrible results with color temp differences..
What I've found is that, once I've gotten the white balance as close as possible for the overall scene, I can go into the HSL panel and tweak colors using the H, S or L sliders on a color by color basis. In Lightroom it applies to the whole image. In photoshop it can be applied via layers to specific areas.
