well xyle, i would hope that your hand doesn't look like habilis hand and that it wouldn't be posed in the same position, with the same wedding ring, a book behind it, etc. there are no rules saying that more than one person couldn't have the same body part.
habilis - nice job in a short time. lots of little details i could get symbolism from if i wanted to - the wedding ring (relates to the whole left hand thing in a way), the words that are in focus enough to read, the pose of the hand - pointing - an extension of the eye. thanks. i like it.
