Well here's Melissa. I was going to have her be Jill's arch-rival but I have had a lot of thoughts. I'd say Jill would be okay to have a some girl cats as rivals but I guess a lot of friendly rivalry doesn't always work out. I could say Melissa is friends more with Jill than rivals.
I was going to have Melissa like Jill be a goth girl but I don't even know what she is yet, if you can tell I'd say she is a prep or a something like that. If I could describe what class she is in I couldn't say yet.
Sometime soon if I ever get the time I will color this picture in.
