This looks like the photo you see in the photography instruction books on the assignment for texture. It is very well done. I would post something more critical to help you improve, but I'm really at a loss. The only thing I see is that the log runs out in the second photo in the bottom right-hand corner, leaving a black sliver of space. But is that a problem? I personally don't think so. And I'd say if abraxas approves with his knowledge of composition and exposure, you've got a decent photo.
