Stunning photo with a good strong composition. There are a few nice little details too: the submerged rocks up close, reflected moon and the cracked ice. Really good.
Out of interest are you using Lightroom? If so can I suggest using the remove chromatic aberration and the dropped to remove the red/blue fringing on the trees top left? I guess it's because I've trained myself to do it but my eyes get easily distracted!

Great pic, Nick. I was working that day and getting phone calls from friends saying how beautiful it was on Saturday. In defence of Nick from the previous comment, the image size limit on UKC means you can only display quite low res images which may account for some of your technical observations.

Yeah, UKC photo limits are pretty damn annoying :( Guess it's not a photo hosting site though so no point complaining!

I wonder if it is chromatic aberration on the tree line, could it be the sensor is picking up more light on the tree line and the green of the trees is showing.

nice composition Nick

Lovely balanced comp...love to see the moon in landscapes, lovely shot.
