First of all thank you all for your nice words!! I created this scene
before the client decided to use CGI or not. I just wanted to be prepared just in case.
And no, the client didn't want to have a crapping bear

. I added it just for fun, because the scene was quite empty. I was looking for a real (not necessarily crapping) model first, but couldn't find a good one, so I decided to use a billboard and found the image of this particular bear. The lighting fit in quite nicely and I thought why not a bear in such a very natural situation?
"...post-worked photo elements..." Yesss! That sounds good to me! I swear the bear image is the only photographic element in this image.
