Depends what you mean by what people think of her, if you mean do we think she likes you or not then i would say its hard to tell based on her just asking you to draw her but it is a good sign that she is comfortable around you which means it would be easy for you to take it to another level ( i also do art and have had this request a number of times)
If you mean what do we think of her in general, well just based on that information she sounds like a nice person.
Off Topic - A little note to you about art though, remember never big yourself up too much or put yourself down too much in regards to art and your art work, if you get cocky your work will get sloppy, if you keep saying its crap you wont improve and see it for what it really is and thats most likely a decent piece of art.
