A black and white forest of birch trees in the winter with a single red cardinal.

Very cool

You can add a bit more detail about the cardinal if you like. Sitting, standing, flying. Chubby bird. Things like that. Have you tried using a negative prompt? I'd suggest the preset under advanced setting but you'd lose some of the details. If you click advanced prompt settings right underneath the prompt box is add another prompt. If you click that move the Toggle to the left for negative you can put poorly drawn cardinal, dull eyes, assymetrical wings, missing limbs that way you get a more detailed bird. If your not familiar with the negative preset it will be on top of the screen when you click advanced settings. Turn on the Toggle then to the right you'll see tweak it. It'll give you an idea of what can be used for a negative prompt. You can edit it for your image and what you don't want. Hope this helps

Beautiful ☺️

Very cool!
