A realistic and detailed image of two Karnathi humanoid characters standing side by side. The male Karnathi is 1.9 meters tall with a slightly darker gray skin tone, while the female Karnathi is 1.8 meters tall with a lighter gray skin tone. Their facial and body tones are harmonized to give a natural, lifelike appearance. Both characters have light gray bone-like scales that contrast subtly with their skin, providing a soft highlight without overpowering the natural skin tone. These scales are smooth and located on key areas, but the only bony protrusions are small and crown-like, located on their heads. The male and female characters are wearing undergarments in a striking color that contrasts with their gray skin, adding a touch of visual interest. Their clothing is simple but distinct, designed to accentuate their muscular and athletic builds. The overall appearance is realistic, with subtle expressions that bring a sense of life and personality to each character. The background is neutral, ensuring the focus remains on the detailed and lifelike portrayal of the Karnathi.
