Sometimes I have the image in my head as to what I want it to look like. Other times when I see the image for the first time in the digital darkroom, I think, what if I changed it to this or how about this. There isn't any real answer to the question. Each of us possess different feelings about an image so an image might look good to you, but not to others.
Here are three images. They are of Number 109, a very handsome looking bull just outside of Obert, NE. Let me know what you like best!
The original image taken right out of the camera.
The image cropped in and converted to black and white and a little structure added.
The cropped black and white image changed to a preset Nik Software filter.
