A Vague Sense of Unease (Poster)

I'm working on this poster for a shop in Hoxton, London called Monster Supplies. It's a sweet shop for kids themed as though the sweets are monster supplies, i.e. eyeball gum balls and this one, 'A Vague Sense of Unease' (Cola bottles). I'm struggling to choose which colour scheme to go with. What do you think?

A quick explanation of the concept. A strange character in slightly unusual surroundings is offering the viewer this glorious product. It looks very tempting doesn’t it? But something’s not quite right, everything seems a bit strange. You really want to take the product, but there’s a Vague Sense of Unease lurking deep within your mind. “Don’t worry... it won’t not bite!!”
