I did this 5-6 years ago. Again...based on Batman the Animated Series. More specifically the episode: Legends Of The Dark Knight, paying homage to Frank Miller's story and style. I posted this one because it seemed like people liked the other one: [link]
I initially did pieces like this because of my love of the series, which produced lots and lots of requests. I stopped doing them because I didn't want to gain a reputation based on the theme and style from someone else. Perhaps in the future I will revisit the theme with my watercolors and sectional style.
