C&C per req:
1. A very nice image. A couple of thoughts for potential improvement: Crop some of the sky off to avoid the half-way division of land and sky, and perhaps try and recover some of the detail in the treed area. I would suggest if you can, try to reshoot this, using a couple of stops of graduated neutral density filter to reduce the dynamic range. I would clone out that little bit of rock bottom left, and also, don't forget to level your images.
2. An interesting composition, albeit with a somewhat yellow/green cast, but I don't really see any main subject. If there had been a bird on the water framed by the two upright pilings it would have worked wonderfully, but as-is, it appears to be missing something.
3. Another nice, quiet tranquil scene. No doubt about it, you've captured the golden hour. Comments, here essentially as per one; G-ND needed and image leans heavily down to the left.
Just my $00.02 worth - your mileage may vary.
