On the first image, Id like to see greater gradations in the grays. My eye is seeing only two grays. That of the sky and water. Then the rest in the foreground. And these are split almost exactly in the middle.

In the second image, I think a bitof camera shake may have made the foreground just a bit blurry? Its not a lot,but just enough to make me want to rub at my eyes.

That said, I think your vision is great. Theyre great images.
