Create a spectacular premium 2:3 vertical social media advertisement for professional Unity 2D game development. Make an original 2D game character the hero, standing inside a beautifully illustrated game environment with rich layered scenery, interactive objects, enemies, collectibles and polished game UI elements. Place a sleek smartphone prominently in the foreground showing the same game in action, while subtle floating development layers reveal animation frames, level design elements and Unity-style development tools behind it. The visual should communicate professional game creation rather than simply advertising a game. Use a bold asymmetric composition with strong depth, cinematic lighting and carefully controlled electric blue, violet and warm accent tones against a sophisticated dark studio background. Premium indie-game studio meets modern technology advertising, highly polished 2D illustration, sharp details, clean negative space, no generic stock imagery, no cliché controller imagery, no clutter. Use an ultra-modern bold geometric/condensed sans-serif font. Exact headline text: “YOUR IDEA. YOUR GAME.” Secondary headline: “PROFESSIONAL UNITY 2D GAME DEVELOPMENT”. Make the headline dominant, perfectly legible and optimized for mobile viewing. 2:3 vertical.
