She looks pretty good for an Australorp, from the picture. I'd like to see some more fluff and depth of body, as well as a bigger tail. There should be a less abrupt juncture between the tail and back. The tail needs to be broader as well. The head looks okay, but it should be broader and larger. Legs are the correct color.
How much does she weight? If possible, weigh her. And Australorp needs to weight at least six pounds to be show quality. And, how big is she? Could you take a picture of her next to a recognizable object or another bird? Australorps are supposed to be large birds with plenty of fluff.
