You know, I take red-eye out of photos all the time. And where's the harm in erasing a zit, or the potted plant that appears to be sprouting out of Aunt Edna's head? You want your teeth whitened, or a soft-focus filter put on? Sure, why not. You think the angle is unflattering and makes you look 30 lbs heavier? I'd say reshoot if you can, but if you really just want the picture to look like you, but more flattering, go for it.
