The only thing about the design that I'm a little confused with is the thing hanging at the end of the chain? I assume it's supposed to be a ball (ball and chain) but it reads more like some kind of combination lock to me. I think it's the size of the object compared to the birds. Make the ball twice the size (if it is supposed to be a ball) and you're golden!
Also, I hate to sound like a broken record, but... CLASSIC FATHEED!
