Thanks again all for your kind words.
Aelfwyn....The arms are two shots of my own arms I took. I created two layers...one for each arm. After adjusting and foolin around to get them to match the gravestone, I set them in place, flatened the image, and did a ton of cloning to get everything to piece together.
The idea for the arms was to create a gravestone, that sort of morphed to life, and the larger it became, the more powerful it was. I shot my arms at an angle to make the hand seem bigger then the arm, to give it that "coming out at you" look. The clouds were real, and to create the fog around the base, I used the clone stamp, turning down the opacity, and taking samples from the coulds.
Im still a rookie at photoshop, so I imagine there is a much simpler way of creating this.
Thanks so much for your replies.
