The two different pics, one with a hoodie and one with a scarf made me think it would be a cool poll to see what people prefer. (For Rayman in general not just these two pics.)
I've always liked the hoodie more especially in Origins where he's always happy, though the scarf definitely suits him in the first 2 games though and I liked him with it too.
I find that the scarf gave him much of that heroic and determination kind of personality and that is one of the things that I liked about Rayman 2 and 1(Mainly Rayman 2, though). It is interesting.
I think the hoodie makes him look more like a teenager in terms of showing style.
I prefer the scarf because there are some Rayman fans who disagree Rayman's current appearance (I mean that he wear a hoodie instantead of the scarf).
But I think Rayman's appearance in Rayman 3 and his appearance in the UbiArt framework are ok, but I prefer more Rayman's appearance in Rayman 2 because I'm very nostalgic and I prefer the 80's, the 90's and the 2000's over the 2010's.
