I like the sunlight and shadow in the shot and you did such a wonderful job with that technique. It looks so difficult to do. I like the background color choices too.
It looks really good and I like the effect of course...the only thing I would suggest, if I might is that you extend the shadow of the animal to the outside of the pic even more than you did...it's not an idea original with me.. It's one I learned by watching Photoshop TV!
We don’t make art to show someone what something looks like. All this requires is eyes (or a lens). Art is supposed to have meaning, emotion, power, or magic. Alan & Mario "FourThirds"
