Semi-realistic digital art with soft strokes and oil shading

Semi-realistic digital art with soft strokes and oil shading. A blonde superheroine with long flowing yellow hair, muscular arms and extremely muscular legs, an oval face, and almond-shaped blue eyes. She should have a serious expression and be in a confident pose with her hands behind her head. The character is wearing a blue bodysuit with the iconic Superman symbol an 'S' on the chest. The lighting should highlight her musculature, emphasizing the details of her muscles. Image inspired by Artgerm. She is on a neutral background.
