Wow you've really got some talent!!
He's wonderful but I think that eyes shouldn't be coloured :/
This. Is. Gorgeous. I love that it's all in B&W except the eyes. The only critique I could possibly give is maybe blend the shading around the right side of his forehead more, so it looks less streaky (unless you were going for a more textured style), and blend the very dark shading right under his lip a little bit more. But overall, great job! This is definitely going in my favorites.
