interesting perspective, only for me I would like to see a little more contrast to the image. Help push it out more and maybe a touch sharper on the bark.
Seems like more of a texture than a pattern. I looks like there are several trees along that walkway. If they were all in focus, you might have gotten a pattern there.
What are you trying to focus on? The tree in the background is distracting and the bark and lichens, which have an interesting texture, are not in focus either. Bring the attention to your subject.
