Create a promotional render of a massive, green, robot dragon standing in the dirt, with a ferocious appearance and patchwork-streak style. The artwork should resemble a masterpiece by Pete Morhbacher and Range Murata, with vivid colors, golden ratio composition, and micro details. The robot should be equipped with a scythe and have a rugged, war-torn appearance, with splattered tar and a sense of having been through a large-scale battle. The style should be reminiscent of a nomad masterpiece, with a sense of a mutiversal tsunami. The output should be in 4K resolution, with top lighting and a focus on ultra-detailed, lifelike details.
