How do artistic interpretations of Batman's costume contribute to the 'coolness' of a comic book cover?

The design and rendition of Batman's cowl, cape, and Bat-symbol are fundamental to his iconic look. When an artist skillfully portrays these elements, emphasizing their texture, flow, and menace – whether it's a sleek modern design or a more rugged, armored look – it significantly boosts the 'coolness' and overall impact of the comic book cover.
