Hey guys, I'm fairly new to this thread but wanted to get some advice on an idea I wanted to write for quite some time. It's about two girls Dillan(black girl) and Xanthe(white girl) getting into a fight in school. The only thing is that instead of the fight being short/prissy where people break it up fast. The two girls beat the living shit out of each other in many different ways without no one stoping them. The idea was that they fight over one of them talking shit and the other punches them which leads into the fight. I just need some help with writing out scenes better and to get advice on ideas I have.
