Your main problem in this tag (and in other tags I've seen from you, too) is that the focal is so hidden in the background. I understand wanting to blend it, but try not to overdo it, or it'll get lost.
Another thing to think about is the placement of your focal, and the resulting flow. Most peoples' eyes will immediately look for a focal point, and if they find it smack dab in the middle of the tag, it kills off a lot of flow. The "Rule of Thirds" describes how placement of a focal slightly off-center of the tag can be highly effective in creating a natural, dynamic flow.
One thing I do like in this tag is the text, but I think it would've looked nicer if it was bigger and positioned closer to the focal.
