Make the small 'Ego' tattoo under the character's left eye look more realistic and integrated into the skin, so it doesn't stand out as much. It should appear slightly faded, as if it's a real tattoo that has settled into the skin, fitting the manga art style. Keep the stitches and pupils deep blue, and the soft, light blue glow in the eyes. Maintain the insane expression and the high-contrast black and white manga style.
