PLANNING: Thriller Opening Possibilities

My idea is to do a thriller that has elements of horror as well as action. I was thinking that we could involve a murder in the beginning. And the shots that are used are highly stylised and contain lots of close ups of props and the character. Something where you can't fully see the character, just a few hints. Stuff like probably their eyes or hands or hair. This is because I think it would create more suspense and it would make the audience very curious as to who she is and what they are doing
