Im not really sure what i think about this topic, still trying to make my mind up....
But anyway, my instant reaction is that i think you have sort of answered your own question in what you have said.
He is known for and loved for, his 'do what i want attitude' for his own reasons and not becuase someone expects it from him, this makes me think that if he is 'changing' then its maybe its just because he feels like a change, an image reveamp, maybe he's simply bored with having longer hair/or his considered typical image.
I think it is also quite a restricive label to try and give someone by saying 'normal', what is normal? who is normal?
I dont think he would think too much about whether what he is wearing or how his hair is cut is typical to what he always wears or wether it is considered too normal. I think that f he likes something he just does it/or wears it, simple no hidden agenda's.
I also think maybe if people try too hard to be different or individual, they themselves can become too worried about giving out that image rather than staying true to themselves.
Anyway, thats just my thoughts, no offense meant to anyones elses oppinions....
P.S Im not really sure theres that much of a big change going on really
