I think it's up to you if you want to re-touch things like that. If what she's got stuck to her shell is distracting then take it out. Some people are die hard that you can't mess with an image after taking it. Why the hell not I say - God gave us PS for a reason
yeah as the guys above said- it's really personal preference about removing those specks. i probably would, as i find them a tiny bit distracting (but i'm not sure whether that's just because you mentioned it!)
