Create a bold and cartoonish YouTube thumbnail with a 'Tank Season' theme for dynasty fantasy football. Depict an exaggerated, dejected football team with torn jerseys and a tank rolling over a football field. The tank should have a big #1 draft pick flag waving on top. The background features a gloomy stadium with a scoreboard showing a losing score. Leave space on the sides for text. Make the design colorful, playful, and humorous to capture attention. --ar 16:9  --c 33 --s 333
