Yeah..."gray"...that's the way it often is. Still, I think the image could benefit from some really careful image processing. It looks to me like the lower tonal values are a bit compressed, or to use the technical term, "all smooshed together". I think maybe the image would benefit from having the Levels set in the red,green,blue channels individually, and then having the tone curve adjusted, so that the darker tones have more what is called local contrast. This is a pretty decent source image, not a really "great" picture, but not too bad. A real Photoshop jockey could make this Pop! visually.
I like the photo - Do you know where in Maine you shot this? Bar Harbor area has some beautiful places to shoot.. I would like to see this same shot on a similar day with the water smoothed out.. not that there's anything wrong with this.. I just prefer water to show its movement over freezing it.. The waves sort of draw attention away from the house, but that's just IMO.. A great photo .. Certainly captures Maine's coastline, & nice to see a beachline photo without the sun shining and beach goers, etc. etc.
