It's hard to truly critique wildlife images, but i will attempt at this one. First off, this image is just fantastic, the colors, the detail, and the overall pose of the animal with the grass in its mouth is just amazing. Composition wise, i like how the otter is not dead center. You can see it in its natural habitat. The blades of grass in front of the otter i find a bit distracting but with wildlife, its very hard to have the perfect setting. I wonder if you might have been able to move to the left and see if you could reach the otter without the grass overlapping the fur coat. The image i find quite humorous as well, which is a good thing. You hardly ever see things like this unless your at the right spot at the right time, and this shows exactly that. A great wildlife photographer shooting a great and unforgettable scene. Overall, id like to have been there watching the action myself, and makes me want to get out and shoot some unique wildlife shots.
