Great shot and you know alot of us have issues with spiders:) The focus is a bit soft in a couple of spots on the spider, colors and contrast work well though.
Yes, this is my nightmare too. Many times. I am terrified of them, so when they creep into my dreams I am ready to scream.
I really like that you have it as a silluette with shallow dof. It works well. It's still pretty sharp as I can see the tiny creepy hair on the legs. You succeeded in creeping me out :-))
I too am not a fan of spider so this does instill a bit of fear for me, if it was more focused though I think it would be even more frightening or better lighted.
Best of all the spiders for this contest. bottom left two lens just slight out of focus, the rest of it is bang on. Very scary, I think that leaving him all black helps too.
