the colors in the first image are mesmerizing. overall its a very monochromatic image, but since the detail is so clear, it seems as though the light is playing with the rocks in the foreground. the reflected sun in the water serves as a very nice transport for the eye from the rocks to the island and cloud formations.
the second image looks like a screen shot from a video game, especially in the sky and with the colors of the rocks. I like the seagull, it gives it some sense of life, unless, of course, you dont want that.
