Aesthetic: Colour or Black and White?

While making this image below for the aesthetic mock-up, I had a go at changing the colours and changed it to black and white to reveal what I thought was a more striking and thoughtful image. Now I am torn between the two...

Looking at the action in the story this image seems far too tranquil, but on the other hand would probably take half the time to create which is good considering the large amount of work making this film will involve.
