This is a very interesting photo. It might have been improved however by increasing the depth of field considerably. It would have really been great if the whole piece was tack sharp. If you're camera won't allow you that much latitude, you might arrange the subject so that the important parts of the picture are all more parallel to the focal plain. Also, it would be better if you would use the whole 150k file size we're allowed. The quality of your picture on the monitor would improve a lot.
the fuzzy spot in the top middle is descracting because its too close tot he foreground. Otherwise it is a great shot. A slightly deaper depth of view would have been great with this complicated object.
