Really: you need more options and much better quality.

That was my phrase: "adorable cute bunny with big teeth, grinning and without background. No cropping, wide shot."

- All of the generated images had a background. What is wrong with generating a png without a background, hu?
!! Make.That.A.Checkbox. !!

- The overall image quality is absolutely awful. I get a 2304x1792 image whit an unwanted background and the bunny is about 1041x1520. The fur is full of bad jpeg-artifacts and blends wiredly with the unwanted background.

- The "with big teeth, grinning"-part has been completely ignored.
