They ultimately ended up looking like they do in the panels above, but Hank’s parents went through several permutations in the design stage…
Well, actually Mother was always based on the actress Chen Pei Pei; in more recent years known for her role in “Crouching Tiger Hidden Dragon“, but who first became a star back in 1966’s “Come Drink With Me“. Most of the tweaks were with the hairstyle :p
Father’s appearance underwent a bigger shift, ultimately based loosely on another Shaw martial arts star, Ti Lung.
(The rationale was that the Shadow Hero could be based off the actor in his younger days, and Father on his older, present, self.)
Finally, a bunch of drawings of young Hank, and young Mother :) Drawings all done with ink, coloured in Photoshop.
Stay tuned for more! :)
