Which cover art style do you prefer?

I voted for the white one for the colour of the banners and text. I like that there's a bit of texture/pattern in the yellow and some variation of tone in this and the text. I feel it gives the graphics more character than the flat blocks of colour used in the other two. Also the green and yellow are happier colours.

From a marketing perspective, I feel that showing less of what's in the pack on the front cover creates more questions for customers as to what else is contained and entices them to look into the pack in more detail.
I think the last design gives away a bit too much and therefore customers might take one look, decide on the spot and take no further interest.
