What is that white animal climbin down out of the tree? The direct on-camera flash is too harsh. You might try some other types of lighting to improve the image. And the fence in the background is distracting. Keep at it. Good luck.
I wish I couold say something good here, but it looks like you saw the challenge and ran out to your back yard and took a snapshot of a tree with a flash. It doesn't appear that any time or effort went into composition, or at least an attempt in taking a good photo. Now, I'm not trying to slam your shot, but when you submit a photo to a challenge, ask yourself if that shot is something worthy of a print hanging on a wall. Know what I mean? I don't see this as something that would make a good print.
the flash has brightened the image too much for me. With less of a flash or perhaps just a long exposure with the ambient light the texture and different depths within the branches would have been more interesting
