Well, I think, for a first time realistic drawing...that the shading is overall well. Could've added more shadow in the ears and the top of his head and various areas on the face. But you know it was a good shot. I love the eyes especially. And I can tell it was one of the main things you focused on. I don't particularly like the lips nor the nose. The nose looks a little to short and the lips are lacking shape. But don't get me wrong. I love the picture! The ring on his ear is a nice touch~!
