Very good photo. The color is very soft and lacks maybe enough saturation. It is almost sepia tone. It just doesn't have any real brilliance or deep colors. 7
Very good shot though I would maby like to see a litle stronger colorbalance or more contrast. I also think that maby this one would score higher if you had croped it so that the pic would only include the face and the main (?, the long hairs on the head, shoulders and chest) of the animal.
Colors seem a bit flat. Maybe try to turn up the sturation some. the focus and light is good. The composition is also attractive. Well done for this challenge.
You get the beat! Great idea. Had you handhelded the camera? It seem a bit blurry. Looking to the grass it is very noticeable. You could to try using a higher shutter speed. A good rule are 1/ISO to stop motion. IE: If you use ISO 100 use 1/125. Using the apperture to control the light.
