There's three (and probably more than I don't know of yet, since I guess it's a common appearance in anime):
Yuki Cross (from Vampire Knight)
Haruhi Suzumiya (It should be obvious what series she is from -__-)
Meiko/Meiko Sakine (From Vocaloid. Technically not an anime but I don't really care)
They all have short brown hair and brown eyes like I do. If you've seen my selfie, I guess it's kind of self explanitory.
If you take away the hair ribbons, I think Haruhi is probably the closest (personality wise, too), but they're all close enough.
