A surreal full-sleeve tattoo design concept showing an astronaut floating through a cosmic dreamscape — galaxies, stars, and nebulae swirling around, blending with elements of nature like trees, mountains, and water reflections. The composition should feel balanced along a vertical canvas (shoulder to wrist), with clear focal hierarchy: astronaut as main subject, celestial elements flowing around the arm, and background depth creating a 3D anatomical sense. The style must be painterly realistic, dramatic lighting (chiaroscuro), warm highlights and cool shadows, high contrast, soft transitions, no harsh outlines, no photo of skin or tattoos. Design on a neutral light background. Add a subtle sense of peace and mystery. Use artistic composition principles for tattoo placement — dynamic flow, curvature, and negative space for breathing room. The overall result should look like a fine art illustration ready to be adapted as a tattoo stencil
