Shout-out To Brett - Great Thumbnail!
A clean thumbnail with a sign or graphic that pops is the best thumbnail IMHO. Use a small sign or a message indicating the major item in your show, or highlight a fun vibe. Use AI sure, but make it tasteful. No one wants a pile of clutter, shocked face, or a messy jewelry pile. That's not unique. I personally need to set aside the time to make a few go-to thumbnails.
