nicely done! The main thing with portraits is recognizing who the person you drew is and you can definitely tell who this is. Love the touch of color on the eyes. There's a lot of black and white on the drawing and not that many greys. Could go also a little darker on the dark tones. But that might be because of the flash when you took the picture. It A lot of highlights as well(limit those to as to to they make the skin look like it's made of aluminum foil) Also like my art professor said(remember not to draw what's not on the picture). But overall you did and excellent job. and P.S. (watch out for the outlined fingers) Keep working!
No, I don't think House died. Wilson did though, ironically of cancer, House just left his medical career to travel with him until he passed away. I think he went into another scientific field of study, but as far I know he didn't die. He drove into a sunset on a motorcycle saying "Cancer is boring". A typical House line, that ended the series as it began, full of vitality and strength doing what it does best
Man, I can't imagine how long this must have taken, and yet you've captured this man's image almost perfectly. I love the harsh shading and the intricate detail, especially on the hair and beard stubble. And coloring only the irises - fantastic!
