Roughed out some ears and booked him in for a fitting of his wooly hat (stretched excessively to get round the ears).
Next thing i guess is a ragged coat with collar turned up.
May lower the forehead slightly to match the pic a lil better...not really getting a good likeness yet but hopefully the texturing will get it a lil closer later.
Sketching out plans for the alley area he will be in... oh and i wanted to ask if its oki with a single render in one position at the end? ...rather than from a few different angles as i have built him with one shot in mind...this will save a ton of work with surroundings an stuff.
Anyways heres a pic.
