What beautiful handwriting...! I love the overall tint of this photograph, too -- what would you call that? Monochrome with a hint of sepia? ..I dunno, but it's good... :)
OMFG seriously embarrassing flashback to my sister's wedding when I tried to sing that line while making bridesmaid speech...and I wa drunk! 8, very good execution and concept, sepia works well.
I love the look of this, from the open stationary box to the calligraphic writing and the sepia-ish tone; only one thing I'd change is the crop on bottom, I'd have lowered it just a weeeee bit.
I can't tell from the letter if she's going to ditch the guy before the wedding? I'm assuming that's the intent here given the 'dear john' salutation. Nice image overall, but maybe making the contents of the letter readily apparent in the parts of it that are visible or even using a title that more clearly reflects your intent would make for an even stronger connection to the challenge. Not voting, just commenting. Good luck.
