Hehehhehe, my favourite of the keys ones. The title is just fabulous :)
A tiny bit more depth of field and perhaps a perspective more angled downwards and it would have have been quite self explicative without the title or the challenge context.
But then, we submit images with titles to challenges, after all :)
Good job!
One of the more creative entries, I love this idea, made me chuckle. I think I'd have taken this landscape rather than have that needless sky at the top of the shot in portrait but if that's your own hand, I can see that hanging the camera portrait would have been far easier for you. Good job on the shot either way, hope it does well.
