I like the texture in the eye and the way the duckweed seems to be enveloping him like the blob. The specular highlites on the skin don't bother me (except for the one by the nostril) as they add to the glistening, wet skin effect for me. I like the one in the near eye (almost looks like a starburst starting). The highlights in the duckweed I'd remove since they break up the color and texture of the green for me.
Dave, I agree with Steve on the Highlights. Removing larger ones recommended. Good work capturing the details. Another image here would be more wide open to demonstrate how well he is camouflaged in the pond. Assuming of course a wider image was possible.
