1: Zone of sharpness seems to be at the rock in the water, and not enough sharpness of the building and trees. Not sure of the context, and where you think we should be looking. Wires center right are distracting. Sky’s blown, but the sun seems to have been to your upper left. Not sure wht that spot is in the tree at the left. Compositionally, the picture has an upper half with the land, and a lower half with the water (with the near side being pretty bright and featureless). I would have liked to see a horizontal crop here, with less water in the lower half.
2: Very nice. Exposure’s good. The positioning of the building is pleasing, and the fading of the mountains to the right is also nice. Perhaps a bit move land at the bottom of the image would have been better, as the building is almost sitting on the bottom of the frame.
3. Very nice composition, but the edge of the mountain in the foreground is not sharp, at least at the resolution posted. Consider placing the sun at the upper third position (1/3 down, 1/3 from left), thereby cropping a bit of the left side. Sun’s overexposed, but unless you’re doing several exposures at different settings, this would be difficult to get right.
4. I see water and rocks. Top rock is cut off, and the exposure is on the bright side (water at the center is almost blown). Overall, not sure what you want us to see in this image.
