A pic that's been on my mind for a while, mostly triggered - as happens so often - by a single sentence in the "History of Middle-earth" series: "The twins [Amrod and Amras] called each other Ambarussa." I could just imagine Maedhros tracking down his younger siblings: "Which of you stole mother's cakes?" Both: "It was Ambarussa!"
Watercolour. (Nothing digital involved here - I even pencilled directly on the watercolour pad. Oh my.)
