The "spear" coming out of her head is probably why she's frowning.
But seriously, I like the natural lighting from camera right, but I think a hair light would have been a nice touch to help separate her from the background and accentuate her hair.
Very nice bridal photograph. Her shoes somehow do not match with the occasion but maybe this is intentionally. A tiny point: the leaf at the right top are a bit distracting. *8*
nice portrait, I'm guessing she's looking away to create a mood or feeling and it works, but I think if she was looking into the camera, if would be a stonger image, but just my opinion, I'm no expert on this stuff
