Don't forget to gel your flashes too. Until they come out with an adjustable white point flash, it would make it hard to fix two different colored light sources.. not saying that's the case here, but it's a good time to mention it while it popped in my head.
As mentioned, the picture is just warm all over from having the wrong WB. Canon does a great job getting it right when outdoors and set to AWB, but for consistency sake (and because I don't know what the camera is picking which would be a good feature) I just set the WB manually and do a slight group edit in post. It's easy to blow out the red channel though and that messes up the skin real bad.
