The Twelve Olympians Picture

Warning: Spoilers for planned Hephaestus characters designs.

This is the contest winner entry for the Hephaestus' Hotrod contest. The winner for first prize, and thus a colored commission from yours truly, goes to Richardil: [link]

(From left to right)
Top Row: Dionysus, Poseidon, Zeus, Hera, Hestia
Bottom Row: Hermes, Artemis, Apollo, Ares, Athena, Aphrodite, Hephaestus

The astrological signs shown on the character thrones are indeed that of the Roman equivalents, save for Dionysus who is sitting in Demeter's seat and Hephaestus who doesn't have an astrological sign.

Demeter isn't in this shot since by some mythology Dionysus takes either Hestia or Demeter's seat, yet there can't be two gods of nature (to some extent) so in this series Demeter let her position go to Dionysus.
Despite popular belief, Hades isn't one of the Twelve Olympians of Mt. Olympus. That is why he isn't in the shot.
Though Helios lives on Olympus (as do Momus and other gods), he isn't one of the twelve and so aren't featured...

Will elaborate on design choices when characters are drawn in their own pages...
