Drawers Block!?!

Not sure if there is such a thing but since drawing that last picture I have run into a empty wilderness.  I can not think of any idea that I like.  I have started drawing a couple pictures in the past couple days, however after getting like an hour or so into the drawing I became unsatisfied and tried to think of other ideas.  I really wish I could get an idea and make it stick on paper the way I see it in my head.
