I love this, great contrast & detail. Good work

The detail and the contrast is indeed great.

I love it!

The only change I'd make to this is to get rid of the blue in the upper, left corner.
Otherwise
WOW

I am constantly amazed at the similarities that we have in common with all forms of life. The network of blood vessels is fantastic and could be either like the structure of a leaf or of my own hand. I wonder if the absence of blubber requires more blood in the cold arctic waters. (I'm guessing a beluga whale)

anemix: Most definitely beluga whale, taken at the Vancouver Aquarium. In the original photo, the blood vessels were not very well defined. Which is why I *had* to make this a black and white shot. They are really quite amazing animals, and the pride of the aquarium.
