The message is clear so it meets the challenge, but it needs something more to hold interest -- somebody holding a handful of them, for instance. Also, the lighting needs work.
But only if the store doesn't go bankrupt, a risk in these troubled times. Diagonal ceiling lights well placed. Tilt of the rack and uneven lighting (as though from a small flash) detract - maybe a small diffuser might have helped.
the flash glare off the cards kind of detracts from this. I think the concept could have worked if you got in closer, and maybe from a more interesting angle.
