Create a comic book-style t-shirt design featuring a superhero character with a strong outline, depicted in a dynamic pose that conveys strength and action. The superhero should wear a cape adorned with traditional Bangladeshi patterns, seamlessly blending local heritage with global pop culture. Use a vibrant color palette, incorporating deep reds, bright greens, and bold yellows to reflect both superhero aesthetics and cultural significance. The text "Hero of the Day" should be integrated into the design in a bold, comic-style font, arched above the character for a cohesive look. Subtle traditional motifs, such as floral patterns or geometric designs, can be added in the background to enhance the cultural aspect without overpowering the main character. In post-production, apply subtle shading to the superhero and elements to add depth while maintaining the flat vector art style. The final artwork should be prepared in a high-resolution format with a transparent background, ensuring it is suitable for printing while preserving clarity and vibrancy.
