Create a vibrant, watercolor-inspired social media poster featuring Yoda from "Star Wars: Episode V - The Empire Strikes Back." Render Yoda's portrait using digital watercolor techniques, with bold, flowing colors that blend and bleed into each other. Use a palette of vivid greens, purples, and blues to capture Yoda's unique appearance. Incorporate splatter and drip effects to add texture and dynamism. The background should be an abstract representation of Dagobah, with swirling mists and twisted trees suggested through color washes. Overlay geometric shapes in contrasting colors to add a modern twist. Apply a subtle galaxy effect in some areas, with stars and nebulae peeking through the watercolor. Use a handwritten-style font for Yoda's name, integrated into the flowing design. Finish with a high-contrast vignette to draw focus to Yoda's expressive eyes.
