Soft Pastel Game Thumbnail Illustration

I need a single thumbnail for my game that feels instantly welcoming and playful. The overall look must stay pastel and soft, with gentle tones that avoid any harsh contrasts. The only element in frame will be the main character, shown from the waist-up so facial detail reads clearly even when the image is reduced to storefront size.

That character should look surprised and curious—wide-eyed, mouth slightly open, body angled forward as if just spotting something intriguing off-screen. No enemies, no cluttered background; a simple vignette or subtle gradient behind the character will keep the focus where it belongs while also helping the colours pop.

Please create the art at 1920×1080 for flexibility, but make sure it still reads crisply when cropped to 1280×720 and down to 320×180. I plan to place the game logo later, so leave 20–25% negative space near the top right.

Deliverables:
• Final illustration in layered PSD (or Clip Studio/Procreate file)
• Flattened PNG with transparency and a second PNG with background merged
• A small JPG preview at 320×180 for quick upload tests

I welcome a quick rough sketch to confirm pose and palette before you move on to clean lines and colours. Let me know your turnaround and any questions you might have!
