Wow, smokin' shot, Len! (BTW, I think it was you that got me hooked on photosig, if I remember right. You submit there, correct?)
I love the strong diagonal created with the out of DOF mushroom in the foreground. As it was downloading, I started to think that I would have cropped the top a lot tighter to the worm's fan, but then when I saw the mushroom I realized that that negative space at the top serves to balance out the shot and does a really good job of it. I think it would be too overpowering if it weren't for that one little area of live rock in the upper-left that breaks up the field just enough. 3TU. :wink:
