Dear Papercut,
Every girl feels like they need to measure up to their bf's exes at
some point in time, & this is especially so when the
relationship is new, like yours. Sometimes it's Not even the
appearance, but how sad your bf was when they broke up, because the
ex(es) obviously meant alot to him if he felt so depressed when
they'd split.
The good news is, this feeling won't last 
I've been
in your position, & I worked up the courage to talk calmly with
my partner about it. I broke the news of my insecurity to him very
gently, all the while reassuring him that it wasn't the result of
any deficiencies on his part, but rather, that it's normal for
girls to feel that way.
He gave me the exact reassurance I needed. And I told him that
everytime I felt insecure, I would always speak to him about it.
Happily, it got less & less frequent, & eventually, I don't
speak to him about it anymore because I don't feel insecure about
his exes anymore.
There must be a reason for his beautiful smiles when he sees me,
& the way he feels fulfilled & contented (which he told me
himself). If you're feeling this way, I would recommend you bring
it up gently with your bf, & let him reassure you. If you
weren't special to him, he wouldn't have chosen you : )
