Female basketball referee on court with whistle and lanyard

A beautiful young female basketball referee, with long straight blonde hair, stands on a basketball court. She is wearing a striped referee shirt with a black collar and sleeves, form fitting black shorts, and a lanyard with a whistle around her neck. The referee has a serious expression and is looking off to the side. In the background, blurred figures of basketball players and spectators can be seen, with stadium lights illuminating the scene. The image has a shallow depth of field, with the referee in sharp focus and the background softly blurred.
