I've created about five or six different characters in my time. If I ever get to actually posting pictures of them, I'll put them up here. ^^
My first character I created is named Hoshi (yes, my username too.) She's kind of a character that I based off of myself when I was younger and I now I consider her one of my original characters. I haven't drawn here in a long time, but if I do over my Christmas break I'll be sure to put it up here.
Another character I created was a catgirl named Bella. No info on her yet...XD
I also have a made up Tokyo Mew Mew character named Mew Mizukurumi (water chestnut) and I based her off of one of my friends who moved to Texas about almost 2 months ago. ^^;
