That's hilarious ^^
It's really funny. I'm a fan of details and this one holds many funny things for me.
The little beans peeking out of the can and one sitting on the toilet made me really laugh. It would be great if the pic was just a little bigger so one could see them in more details, but still they are great.
Those popped out eyes on the can look cool, too.
The only real problem is, what has been said already. The mixture of softness here and sharpness there can be quite confusing. Good thind this is a crazy pic, so it's not a serious issue in that case.
And I must agree, a background would have been a good idea. But not too much, because there's pretty much going on in this pic already. ^^
It kinda reminds me of one of those matryoshka puppets. You know? Those female russian puppets which you open and find another, smaller one inside and then another and another... only that this a bean with a bean can on it and a bean on that. :P
