Professional YouTube Thumbnail Design Needed

I need a striking thumbnail for an upcoming YouTube video and want it to look Professional level—clean, polished, and instantly clickable. The final image should be sized for standard YouTube dimensions (1280 × 720 px), optimized for both desktop and mobile displays, and delivered in PNG plus the editable source file (PSD or AI).

I’m open to your creative direction on colors, fonts, and graphic elements as long as the finished look feels refined and high-quality. If you think a minimalist layout, a vibrant color pop, or a darker dramatic treatment will help the thumbnail stand out, let me know your reasoning and show me a quick concept before finalizing.

Please include:
• Two initial design options for review
• One round of revisions on the chosen concept
• Final export in 300 dpi PNG and layered source file

Experience creating high-converting YouTube thumbnails is highly valued. Share a brief note on your approach and a couple of recent thumbnail samples when you reply.
