Upper Body: The ribcage presents a smooth surface, with subtle indentations where the ribs lie beneath the skin. Faint striations hint at the intercostal muscles, contributing to efficient breathing and core stability. The musculature of the abdominal wall is meticulously defined, showcasing each individual "six-pack" muscle (rectus abdominis) with bold relief. Deep grooves separate them, revealing glimpses of the glistening obliques beneath. The abdomen is like a finely detailed roadmap, with a play of light and shadow highlighting each muscle group. The texture is not smooth, but rather a tapestry of striations and subtle bulges, signifying the immense power contained within. Despite the definition, the musculature maintains a feminine aesthetic, avoiding an overly bulky appearance. The lumbar spine exhibits a slightly more pronounced inward curve (lordosis), creating a graceful arch that accentuates the S-shaped silhouette. The lower back sways gently, hinting at controlled tension in the core muscles without rigid hyperextension. While the individual lumbar vertebrae are not visible, slight indentations at their base suggest their underlying structure. The waist is the focal point of this ultra-detailed portrayal. It dramatically dips inward, creating a striking contrast with the wider hips and chest. However, it maintains a natural and feminine form, with a smooth indentation that seems impossibly small compared to the upper and lower body. The transition from the torso to the hips is seamless, without any abrupt jutting or dips. Tracing a line across the lower ribs seamlessly flows into the curve of the hips, accentuating the incredible definition.
