The characters sharp posture gives a calm yet alert presence. Behind him, dark metallic walls converge, displaying glowing holographic panels, while a vast starfield with scattered crimson nebulae dominates the large windows beyond. Subtle particle dust floats in ambient light beams cast from above.
