Your proportions are quite off, and your topology has taken a step backwards in my opinion. Take a look at the muscles in the face, this is what topology is based on.

Under that beard is the same muscle flow as everyone else. You shouldn't have to change your underlying topology in order to match it to new characters. You simply augment them instead, cutting in more details when needed.

Also make sure you have reference material while you're working. However you must get the hang of looking at shapes and form in the perspective window rather than simply matching in the orthographic views. Take a step back and be critical on your model. Is his chin really that sharp? Probably not. Does it stick out that far? Probably not. Are his eyes that small? Again, probably not.

Also, I would highly recommend that you finish one project before starting the next. It always sucks when it comes to an interview and you don't have a single thing finished; only partially finished things.
