I see a fair amount of muscle definition in the right leg (the one deeper in the water). Still, the degree of muscle definition seen on the various body parts is kinda lopsided. Plenty of definition on abs, definition on one leg, no visible def on the other, arms look like she doesn't work them at all... weird.
