stefan salvatore just jumped

I have to do my own crime drama and i need help creating a really good poster for it. Its called Vamp-Cops. So its based on the vampire diaries webisodes and I just put my own twist to it. Basically what its about someone who kills this persons sister and its the same someone who turns him into a vampire, so he wants to find the person who killed his sister and that is why he wanted to be a cop. He makes a friend with a cop and she is also a vampire, in each episode they get closer and closer to find his sisters killer but they dont relise that they are walking into a trap. (I might not be the best at explaining things lol or spelling) Message me if you want to help :D
