What should I write about next?

I have so many ideas and I have no idea what to write about now. I have Sleepy Hollow(my favourite TV show because of Tom Mison), Beauty and the Brute(Beauty and the Beast cross/ mess-up thing), Revolution(where my OLD OLD OLD OC is put up for bidding to be married. It's weird), Law and Order: Criminal Intent Equestira(LO:CI crossover), Drowning(New OC is killed) Going into battle(New OC is realated to Sombra), and that's it right now. I'll kill ponies, I won't MAKE ponies(If you get where I'm going with that). I'll also add in your OC if wished for in the comments. Otherwise, please give me some ideas for this.

THANKS A BUNCH!!!
