This is great, the branches almost slither around the larger fox. The mood is excellent, it makes you feel as though you've been put right in the middle of a story. I also agree that it's got a very nice texture.
This reminds me of my favorite child hood book, Watership Down. I love the texture and grace in your drawings, as if done with a slight of the hand, but given a lot of detail in the finish. It looks very natural and comforting stylisticly, but the subject matter is effectivly unsettling.
