'Where's Wally' style YouTube thumbnail design required

I am looking for a talented illustrator to create a captivating "Where's Wally"- style YouTube thumbnail. The ideal candidate will transform a hand-drawn sketch into a vibrant, intricate illustration that invites viewers to explore and discover hidden details. This project demands exceptional drawing abilities, featuring numerous small characters and scenes with clean, legible line work and a thoughtfully curated color palette. The final deliverable should be a 1280 × 720 px PNG file, accompanied by the source file. I have attached a rough sketch of the design to give you an idea of the detail involved.
