Good shots. Two things I might suggest if you want to try them on a later shoot:
Add a slight warming gel. I like using a 1/4 CTO during Sunset if I'm shooting into the setting sun like this. Get the flash off-camera, if you can. If your camera has a popup that can act as a commander, get it into "--" mode and just hold the SB800 in your left hand above your head and as far to the left as you can get it (or have someone else hold it). It'll greatly improve the quality of your light. I also use the following setup to achieve this very often:
This gives you a great way that you can hold the flash and the camera and still get the flash signfiicatnly off camera. YOu can also ask someone else to hold the pole for you as a voice-activated light stand.

I agree with the need to get the flash off the camera. I would also suggest varying the output of the flash to blend the subjects in the brighter photo so the do not have that stuck on look/washed look. An inexpensive bounce card may also help.
