This is quite the collage of flowers, and the variety of color makes the painting burst with life. I like the way the paint spurts out from the flowers around the edges. You also did very well on the eyes, lips, and hair. I am particularly fond of the way you textured the hair. The string of beads adds the perfect touch, and ties in nicely with the flowers.
I would suggest working on the chin/neck. On one side the chin is quite far down, and the neck is indistinguishable, and on the other side, the cheek seems too sunken to meet up with the chin properly. Other than that, this piece is beautiful.
