Professional Youtube Thumbnail and Digital Banner Design for Enhanced Engagement

I am seeking a talented graphic designer to create a series of eye-catching and professional YouTube thumbnails and various digital banners. The primary goal is to produce visually appealing assets that are optimized for engagement, driving higher click-through rates and attracting more viewers to content and promotions. The designs should be creative, reflect a strong brand identity, and effectively communicate the core message at a glance. I need a designer who can deliver high-quality visuals that stand out in a crowded digital landscape. Please provide examples of your previous work in digital banner and thumbnail design.
