Its a decent model and i like how it's coming together, but it just doesnt look like good old Sean. For starters it looks like theirs too much distance between his nose and mouth, and as for the lips, I think the shape is off by a little bit. The lines coming out of his eyes are also off and need to be stretched more, and I think his forehead is a little too pronounced. Good work thus far. Keep it up.
Death is certain, Life is not.
