I'd advise to be paitient for now..
Keep talking, as they always say the best relationships come out of friendships first?
Stay in touch with her, just so she has the idea you're interested..
Then when you feel more comfortable and you're assured that she is interested too, go for it
And no, that would not be a reason not to like someone, unless they are very shallow.
In which case, i'd say you could do ten times better anyway, anyone who put that as a reason, wouldn't be worth the hassle, you're willing to make
Good luck :3
