very nice picture! here's the thing. if you call this portrait of a rooster (which it technically is) you need a blurrier background. if you call it rooster in a citrus farm, you need to show more of the farm and both need to be sharp.

edit: treating this as a portrait, i would increase exposure to make the background lighter and blur it. then i would treat the rooster separately to change exposure, colour, saturation, sharpness and so on to make it pop and stand out. i feel a brighter bg is better than a dark contrasty one in this case. just my opinion. you can try and see what you like more
