Filming

Well we have now nearly finished filming. We have done the title sequence scenes, house scenes and river scenes, but we may need to add to the house and river scenes due to some continuity problems (the actress isn't wearing any shoes in the house scenes but is in the river scenes!!!) I thought that once we had filmed it would all fit together nicely but i'm not happy with the end result-it doesn't really seem like a thriller to me. I no it only needs to be the opening so it doesn't have to make sense, but I don't like our opening and I can't think how i can improve our idea- can anyone help?!?!
