Oh, you don't have to change it if you don't want to, but it is something to consider. (Personally, the greater distance you can put between this project and that existing franchise(?), the better.)

I still think given her ears and horns, it would be cool to base her fangs on a Muntjac (or, as I call them, "Fanged deer"). They even exist in Indonesia. How's that for coolness points? ^_-

Also, I came across this ugly mug. Having more pronounced upper canines makes more sense to me anyway, since the lower fangs on animals usually tuck up into the upper jaw, as opposed to jutting out and away from the mouth like the upper fangs.

Just my two cents, as always.
