I think that this piece is absolutely gorgeous. I like the shape and size of the eyes and how the pop out with the large eyelashes. Her body is delicate and it gives her a very nice feminine touch. I think having the girl off center slightly is nice because your eye isn't just centered in the middle of the photo. It looks to me like the smoke kind of turns into, or blends into, a tree. One thing that I think could be drawn/painted a little differently would be the tongue. It doesn't really look like it's coming out of her mouth, more like its just stuck onto her lips. But, overall I really do like this piece of artwork.
