Firstly your white balance is off because you're shooting your subjects with daylight in a tungsten environment. Mixing light gives inaccurate colours of skin and more importantly the clothing.
But the flash is still somewhere between 5500K and 6500K while the practicals are 2900K to 3200K.
So it's still a mixed light environment and unless you can run out and place the grey card next to the models face you're not going to change anything. Plus that mix is going to change as they move through the room and their proximity to the practicals changes.
Well Dan you sound awfully sure of yourself but I don't think you understand the issue I was discussing with BrianO.
The warm light from the light fixtures in the room leave the color balance of the images skewed by their influence. The flash is balanced for one color temp and the room is much warmer. Since the models are walking through the room that influence can also create a color cast where the flash isn't fully controlling the light that falls on them.
Gelling the flash to match color of the practicals helps resolve the problem, everything is balanced for one color temp. or is at least much closer. Dimmed tungsten lights will drop down to 2600 to 2900K and a full CTO gell corrects to 3200K. So there still may be some variation.
I use a Minolta Color Meter to check the practicals and gell the output of my flash to get as close as possible.
