Yup as Zen said... Hayley needs some brightness.
And I think that the lightning source should be less bright
The lightning source is kinda the focal for me now.
If I look at the sig I then Hayley doesn't get my intention.
She not popping out enough IMO.

You've created a nice flow and I like the effects
I don't really like the colors... but I guess that's just my taste.
The lightning source has no effect on Hayley atm. Try to give the right side (for us) of her face some brightness and darken the left side a bit.

Keep working at it mate
