I like it, very different. It seems a bit soft in appearance for what looks like concrete. Your file size of 92k indicates you may have used more compression than youhad to. compression kills detail. Always use the least amount you can and still fit in under the challenge limit.
I hate saying this but there is no square content. As with some others in this category it is a really good picture in itself I actually quite like looking at it. Falls into the category of picture that can stand up in its own right, doesnt even need a caption.
