I like it. It really gives a feeling of life around the pier. You have controlled the depth of field to draw attention to the most interesting portion of the scene. Did you get wet taking the picture?
A watertight camera would and being slightly underwater would make this a better shot, just kidding. Cool photo the depth of field gives it a sense of distance to the pier.
nice side lighting -- like the way the nearer barnacles sort of blend into just a texture as you get further away from the focal point -- don't now what to suggest to make it a better image -- maybe a slightly less centered composition?
I really like your perspective on this photo. The detail in the foreground is great! I can also definitely tell that I am looking up :) I have also, during preparation for this challenge, learned how to achieve this shot and maintain proper depth of field to keep everything in focus. You simply have to step back about 18" from this pole. You don't have to put yor camera right on it. Nice job!
