In complying with centuries-old traditional design parameters for the King of Hearts, the tip of the blade is non-existent. Some historians believe this is because it was originally an axe that got converted into a sword over the years. This is what gives the illusion that the king is stabbing himself in the head, hence the nickname of “Suicide King”. I linked to an explanation in the original post.
This particular illustration was done in graphite, scanned in, and colored in PhotoShop. Other work on this site was done in the same way, while still others had color added to them by more traditional means (painting, colored pencil, etc.). I never know what tools I’m going to have on hand when the doodle urge hits me, hence the wide variety of media and techniques.
