Create a dramatic and powerful dungeonpunk-robot concept art with a barren earth backdrop and a purple sunset, emphasizing a 5-fingered robot with extreme detail and a strong, full-body presence. Incorporate the styles of Artgerm, Greg Rutkowski, Alphonse Mucha, and Simon Stalenhag. The image should be rendered in high-quality, photorealistic detail, similar to a digital painting or an Unreal Engine 5 output. The focus should be sharp and the overall aesthetic should evoke a sense of cinematic beauty.
