Thanks for the feedback, folks, I appreciate the kind words. Though after reading the first few responses, I was beginning to think I may have to push the house over the figurative cliff.
I could clone it out, and that would help solve the other issue that some of you have mentioned. But I've had the same debate within myself whether, on balance, that would add or detract from the image. It's good to hear a variety of opinions.
Now to the horizon. I know that it appears to be a bit tilted up on the right, but it's actually not. (Take a look at the house; its side is vertical.) There's a peninsula out there that gets closer to us on the right, which yields that illusion. I have already corrected for it a bit by tilting the image down on that side a little. If I do it much more, the house will appear to be leaning. (Maybe that's good a good thing, and it will slide on into the ocean.) I could use stretching to correct for perspective, I suppose, to avoid affecting the left side so much. But it was my feeling that the apparent tilt of the horizon wasn't that bothersome. Seems like maybe it is to others, though, since it has caught the attention of some of you.
