Hmph! I can't believe that someone would say that about your art. >=\ She needs a new pair of eyes.
Anyways, I just adore those pictures! You have such an adorable style, and don't ever feel that you should change it. That style is so unique, and cute! I just love it. Those are very nice pictures! ^_^ Don't worry about what that girl says. If she would say all of that then she doesn't deserve to be called your friend. Atleast, not until she changes her attitude. Even if she didn't like it then she shouldn't have been so mean.
