Love the text, but I don't like that blue light beside her head. And the white effect to the far left is a little distracting.
I would remove the blue light to the right of her head and that white thing on the far left. Last of all im not exactly sure what it is but theres somthing about her face i don't like.
lighting. i don't see a light source.. and wtf is that thing on the left?? lol. anyways, the text is big.. but thats how you have always done it so i dont mind. i love the effects, but the lighting makes the whole sig look kinda odd
