Although the idea isn't actually quite original as I have seen plenty picture of this style and pose, however I liked the overall view as the smoke actually divides all view into two parts - full of smoke and a little smoke which adds some kind of mysteriousness to it.
Facial expression is quite "hard" and would't look so pretty if not for those eyes who makes it all look a little bit different - a little bit mad, a little bit resentful as they say "You know very well what you have done, man!".
As I like colours very much and there are only few picture I like without them so this one satisfies me completely as these red-blue-pinkish colours actually quite reinforce the overall feeling.
The only thing I don't like are the light coming from the right with the smoke as it makes that side look pale and too not-interesting so it makes the left side more severe as right one.
how did you make the smoke and how did you add the color to the smoke? was it lights? how much do things like that cost. this is gorgeous work and i've been wanting to include smokey things in my work for quite some time.
