K...ThIS IS Way tooo CUTE! I love Squirrles and now I love them even more! I really cant tell you how much I adore this picture! The pose is killer along with those cute little eyes that are highlighted with the white!
The balance of the overall picture is great! The eye travels easily over the branch to the pines then to the background. Im liking the fact that the background is blurry it allows the eye to see the Squirrle better. You really got close enough without being too close. *hope that makes sense* There is really no lighting or shadow to talk about. However, it doesn't make this picture any less awesome. I think you pulled it off quite well without any lighting!
