I kept looking at your shots and something kept bugging me but I couldn't put my finger on what it was until now. Most of the space is in the back of the boat except for #2 and that does the same to me as portraits with more space at the back of the head rather than in the looking direction. If it doesn't bother anyone else, I guess I am just showing how weird I am, lol.
Other than that, I agree that the white light in the lower left of #1 one is annoying but, even more so is the fact that I feel it was shot through something. I'm seeing lines running up and down and tones that don't seem to fit. And in #4, I would have moved the picnic table or cloned it out.
The light in #2 is my favorite.
