A very nice study because of the rich texture and the lighting very natural. The only thing I would have done diffrent is to have changed the angle a bit to avoid seeing the support stone that comes off the heel of the left foot.
Nice colors. I love the green under the feet and the way the dark brings up the light . Maybe a little too close up though. Back off just a little to more closely follow the rule of thirds in balancing out background vrsus foreground and light versus dark. Great title and conveyed well by the the picture which showsthe feet hovering. The texture of the stone is shown to advantage.
