Dave,
I really like this shot BECAUSE of the unusual angle. In looking at it closely, the foreground is well-exposed and has nice detail and the background of the lake and mountains likewise is well-exposed and has lovely detail. The middle area -- the trees, etc. -- seems a bit muddy to me and I think there's more detail you can pull out of it. I'd try tone-mapping in Photomatix just to bring up that shadow detail and I'm betting you'd like the overall image better.

Nice shot.

Jim
