Hi Dan,

I think the last one looks the best - possibly still a bit too strong in the sky though. The thing to remember with light is that in nature the light in the sky will "contaminate" (or influenece) the colour of everything it illuminates. You can see it in the water, but it just doesn't seem to have affected the ground as much, which is what makes it look a little un-natural to me (which is why I pulled the saturation of the sky back a bit in my version).
