Interesting structure/texture but I fear that
(a) the slight unsharpness at the corners/borders disturbs me (more than I like
(b) the image as a whole is not interesting enough for me
Same happens to me when I shoot signs on the bark of a tree: I find it interesting, but fail to produce a real good image.
Perhaps showing part of a word would make this type of shots more appealing, as the brain has more to work on than just a simple letter and a texture.
