After doing some research, looking through other cosplay poses, I have found that no one has done this exactly. Some may bring their leg up to simulate the beginning of a kick but you have done a complete kick. Looking through my memory compartment, throughout the One Piece series Sanji has made this exact pose which I believe you know. The hair, as said in the One Piece wiki, is combed out well, I believe you got the hair style down. The eyebrow is curved almost completely, from the angle I am looking in. The outfit that you are wearing is spot on, the facial expression might not be completely correct because Sanji has an angry expression most of the time. When he is around women he acts like a love-struck man, when people love his food he is very happy. I have never seen the cook expressionless, also the cigarette is white, not black. I am very picky on the little details, my apologies if I am incorrect. Otherwise, overall this is a very good cosplay of Sanji.
