^ Since I am a big Who fan, I might be biased. But Keith was said to have big brown eyes, so is he the one between Pete and Roger? John was also said to be quiet and uninterested, so the look on his face kinda seems like that...
Edit: I am not judging your drawing at all, and i think it's super good. But if that is supposed to be Roger on the end, he never smoked because he didn't want to ruin his voice. But like I said, it is really good!!!
