Edit this Pixar 3D style character portrait. Keep the SAME face exactly as in the reference image — preserve all facial features, the large expressive light grey-blue eyes, eyebrows, gentle smile, lip shape, skin tone, and blonde hair color and texture with bangs. Restyle the hair so it is tied back in a ponytail secured with a fabric scrunchie, keeping the soft bangs framing the face. Change her outfit to a fitted yellow sport tank top (athletic/gym style). Keep the silver rhinestone cross necklace clearly visible on the chest. Set the scene inside a modern gym with bright, clean gym lighting, subtle equipment and mirrors softly blurred in the background bokeh. Maintain the smooth stylized Pixar 3D animation rendering.
