I have been asked to comment on this image. While many would find the limited DOF distracting, I like it because it draws your attention to the subject. The frog is sharp and clear with no DOF problem. My only suggestion would be to try and show more of the frog or increase your f-stop to increase DOF. Saying that, I have shot more than my share of frogs and know that they tend to move if they feel threatened. I would rate your image as better than average. Nice work!!
