Without looking at the title I thought this was the side of a mountain of large rockface. It's very good picture, really good lighting! Not sure if sharpening it a little would have helped this picture. Well done!
I do like tree bark but IMHO the incident lighting just does not seem to do it justice. Maybe a little more sharpening would have given that "zip" to make it stand out. Not sure.
The contrast of the lights and dark of the shadows and highlights really bring out the texture of the tree trunk. You eyes follow the trunk from the right hand side where the subject is bright toward the darker shaded side of the tree. The angle you chose gives the sense of the roundness of the subject. "9"
The movement from light to shade, and the broken nature of that surface is well captured. Photographically, a difficult composition - one's eye searches for patterns in near-abstract images such as this, and there is a sense of two stonger horizontal lines in this surface, but they lead me only to the silhouetted edge of the tree - I think I'd have tried a wider aspect ratio thatn this 4:3, to bring those lines closer to top of frame, then the combined lines of the edge and those two would produce a triangular feel with the brighter area of bark: might (only might) find that the eye moved through that more happily.
