Design an intricately detailed, cinematic portrait of an Icepunk soldier with a gun, inspired by the Imperium Space Marines and cultist aesthetics. The character should wear a black greatcoat, have blue skin, and exude an air of charisma and high moral intensity, as if a sexy werewolf. Incorporate hellhounds and metallic asteroid elements into the background, and draw inspiration from the works of Masamune Shirow, James Jean, Greg Rutkowski, and other mentioned artists. Ensure the artwork is symmetrical, dark, and steampunk-themed, with a focus on eldritch, blue hues, and intricate details. The final piece should be a high-quality, 8K, octane render, created using ZBrush, Maya, or similar software, with a style reminiscent of the mentioned artists and a sense of depth and atmosphere. To achieve this, the AI should first analyze the core concept and identify key elements, then layer details and context through iterative refinement. The AI should alternate between reasoning and acting steps, incorporating self-reflection and evaluation after each action. This process should involve breaking down complex aspects into manageable sub-tasks, gradually building complexity, and incorporating instructions for handling multiple art styles and modalities. The AI should also generate background knowledge on key concepts in the subject area, such as character design, art styles, and software, to inform the prompt enhancement process.
