This is a very beautiful work. I don't know the Movies & TV character, I'm sorry, so I'm saying what I think viewing your image.
Like all tones of red and pink that you've used to give a personality to the character that you've painted. The dark red of her eyes and lips makes a very interesting combination with the light red of her hair. Also, I think that she has a very nice haircut. Good work with her facial expression, she passes us the ideal of neutrality.
it looks pretty nice just one thing... im no expert on nothing, but that dress... the pattern u chose maybe it was not the best, u should "paint" it so it looked more real, i mean, it follows the bends and turns of the dress itself or even the body of hers anyway, liked it
