I actually really liked the hair, the way it falls gives a distinct idea of the shape and stiffness of the leaf, although I think it could be even better with some more detail in the flower parts (veins in the leaf etc). I think the colours work very well together though I would have liked to have seen a little more red in the flowers nearer her face to her skintone would 'flow' into the flowers a little more. But perhaps this is not the effect you want. I think it's a beautiful and well compositioned piece.

Some really impressive tonal control there and a 'neat butts' arrangement. My only issue is that the hair gets a bit muddled as it strands down
