Bold Colorful Illustration Thumbnail

I want a bold, colorful thumbnail that instantly grabs attention in crowded feeds. The design should communicate energy and style through pure imagery—no text overlays or additional icons—so composition, palette, and lighting must do all the talking.

Custom illustrations are a must; please avoid stock photos or screenshots. Feel free to sketch in Procreate, Illustrator, Photoshop, or any drawing tool you prefer, as long as the finished piece is delivered in a layered file (PSD, AI, or high-res PNG with transparent background) so I can adjust minor details later.

Primary deliverable: one web-ready thumbnail at 1280 × 720 px (or square 1080 × 1080 px if that suits the artwork better) plus the editable source file.

I’ll review based on visual impact, originality of illustration, and how well the colors stay vibrant across devices.
