Refined Prompt: Create a hyper-detailed, 8K ultra resolution illustration for a Facebook welcome post promoting an AI art free class. The graphic should convey a futuristic and innovative mood with a mix of cool and neon colors. The style of the illustration should be realistic and detailed, utilizing a digital medium. In the foreground, feature a laptop, mouse, and mobile device with metallic textures and reflective surfaces. The background should consist of abstract shapes and patterns that enhance the futuristic theme. Position the text "Welcome" in bold, modern, and large font at the center, with the text "Class will start @9 PM" in a smaller, elegant, and classic font below it. Use soft lighting with a hint of backlighting to highlight the computer elements. Apply subtle color grading and HDR effects to enhance the overall quality of the illustration.
