I like a weird girl?

I really like this girl who seems strange to me.... She's really into Japanese cartoons, she's extremely shy, and even works in an anime store. She's incredibly enveloped in her favorite characters from the shows and seems severely unattached to society. Lately I've started watching Bleach and Naruto that she recommends so we have more to talk about. I've even bought anime t-shirts from her and wear them to work. I visit her every weekend when she works and I try to do something nice for her. Last weekend I made her a painting I did for her of an anime character she likes. And just today I delivered her a pizza from the restaurant where I worked for free (which was a surprise.) She was wearing a kimono to work today which I thought was strange, but more so I think is cool. I've never tried to make her feel weird about her actions. I want her to know I think she's special and different. I've known her for about 3 years now, and she's always been like this; herself... Just lately though I've really started to see the beauty in her personality. How can I let her know that I respect her, am interested in her, and want her to know that I like her just the way she is??
