Shadows aren't necessarily "stupid," but I don't think they work in this image. Shadow on face to camera left is too light: it just covers without truly dramatically obscuring, and blurry edge is distracting. Shadow on face to camera right is much better. Neutral expressions don't really work for brides, IMO. Aspirational, nervous (well, she could be nervous, but not happy-nervous,) happy, dreamy, those all work, but not the Mona Lisa thing. Bright glaring stained glass is too small an element to be integrated, too big and oddly positioned to be a simple accent - I think I'd lose it.
This picture displays a "really close" quality that I am all too familiar with from my own work. *sigh* Fix that leftside veil, perk her up a bit, and drop down/zoom in, and you've nailed it.
