Oh my gosh, that is absolutely beautiful! You did a gorgeous job of capturing this beauty~ The detail in the eyes - normally a spider's eye looks black, but you've managed to show that it's not so. ^^ You've done beautifully, good job!
Amazing work! One awesome model you had there too (: Might I ask you about the lighting conditions? Judging from reflections in the spiders eyes, I see two diffused light sources (flashes most likely?) from above and a white reflective source (sheet of paper?) from bellow, however, what confuses me are those strange cloud-like reflections in the mains eyes. How did they come to be? Is it something from post processing?
