白色背景上行走的像素風男性刺客角色貼圖

A high-quality 2D pixel art sprite of a mysterious male assassin, viewed from the direct front (facing forward). The character's face is completely covered by a sleek, matte black tactical mask and a dark hood. He is wearing a dark charcoal grey stealth suit with navy blue accents, utility belts with pouches, and strapped daggers on his thighs. He is captured mid-stride in a forward walking animation pose. The art style is crisp 16-bit pixel art with vibrant colors but a dark aesthetic. Full body shot, isolated on a solid plain white background. The sprite should look clean, with distinct pixels and no blur, perfectly suited for a video game asset.
