Great capture! The rocks digging into the sand is absolutely striking. The sea in the near distance in a slight blur gives this photo an ethereal mood.
Nice shallow depth of field (in a few of your shots). Effective in helping your viewer focus on the foreground. You really did a nice job on this assignment overall.
Nice texture shot! I too like the deep color of the rocks and the way you burred the background. Nice use of the Rule of Thirds at the bottom right intersection point.
