Great drawing. This is exactly who I would have chosen to represent Zenyatta.



As for the remaining heroes, this is my 2 cents...

Genji-> Celestia: The sibling who has attained mastery and is at peace.

Honzo-> Luna: The sibling who made a terrible mistake and is trying to atone.

Bastion-> A powerful shape shifter character, do you know a good shape shifter besides Discord or Chrysalis?

Torbjorn-> Sunburst: A brainy intellectual, who prefers to work behind the scenes.

Roadhog->Tirek: A ruthless giant, and partner in crime of Junkrat/Discord.

Winston->Fido: A hulking gorilla shaped creature.

Ana-> Cadence: A loving mother who prefers healing, but is still a deadly fighter. Arch enemy and foil to Widowmaker/Chrysalis.
