I'm the same with eyeliner not matching but I think it's more just lack of practice. Sometimes I get the left eye perfect and the right eye just won't look okay, depending on which I do first.
I think make-up can be fun to play with and dress up, particular
for photos but I'd rather take photos of people who actually want to model.
Also I almost never wear make-up and used to constantly get crap for it, even in secondary school, by teachers, where you weren't meant to be allowed to wear make-up. Although they may have just wanted to move me off dying my hair.
