I am the one who already recreated this picture, but with a different technique http://giuseppeguzzardi.cgsociety.org/gallery/537235/
It’s nice to see the old gentleman here again, he is becoming a real star!
As to your work, I have also thought about doing the image gain the way you did, sculpting more detailed the face and recreating the skin and a new texture for it, and eliminate all light effects and create a character which can be reproduced from all angles
but for me “Signs of Time” is a concluded work piece and I have learned a lot from it.
I like your clothes; the skin though seems a bit artificial and I think the background is a bit to blurry.
I do agree however that this image is under your normal standard I am used to see your amazing works that I really admire.
