Animation Update Colour Choice?

Although it seems that I like to keep everything hush, hush, I thought it would be great to get some comments on what background seems better. As even with my animation the feel is not coming through yet until I have the colour backgrounds completed. Although I do have a lot done of them, I have two versions, one a minimalist to show off the main two characters and the other filled with...a more dulled down colour sheet. Tell me what you think!

So here they are...I must admit I am more leaning towards the first one with the hues of white and black simply because it makes everything seem...so barren. I don't know really.
