Beautiful image. Colors are stunning. The sky is very intense.
The entire image appears to be slightly out of focus an unsharpening mask might of helped. The bouy appears to be something for the eye to look at and you may want to try to pull it up more next time and make it appear closer and bigger rather than just being an object.
I thought a while about this as to if it fits the image and I would say it does make me want to relax and since home is where you relax it does say home sweet home. Nice interuptation.
If this is a view from your home or to your home you're very lucky. If it's a view OF your home you may be a fish. This is quite beautiful and words aren't really necessary - the picture says it all. This could only be improved with increased DOF yielding a sharper fore and background.
5. Fits the theme well enough, and there are no blatant 'you suck!' flaws to it, but neither does it really grab me for any reason at all. For reasons of composition, cropping, or subject choice, it's just a photo, and doesn't do especially much for me, aesthetically.
The colors are very pretty, but there's just nothing for the picture to be about, no center of attention where the eye is drawn.
