How about a male, night elf Shadow Priest and a female Draenei Shaman...holding hands, skipping through a field of roses. NO, running to one another on a beach at sunset. Or even, drinking the same chocolate milkshake with two straws.../sigh....yes...
Or some other cool moments like, High Inquisitor Whitemane ressurecting Mograine. Easily titled "Arise, My Champion"
The nearly tearjerking (if you played W3) scene of Maiev Shadowsong kneeling in victory after helping you defeat Illidan.
Something involving a face looking past the "camera," most likely off into the horizon at his/her next undertaking.
Or, if you want to move away from WoW...I know Bill is a Final Fantasy fan like myself and there is a myriad of amazing scenes to depict from that. Like...
Painting Kuja from FFIX would help to show some versatility if you could show his effeminate traits yet maintain his masculinity, all while keeping the somewhat cartoonish look of the game.
The scene of the clouds rolling back and the cherry blossoms bursting into the air as Rinoa holds up Squall's head from the ending credits of FFVIII
Me eating a bowl of clam chowder
Garland, knocking us all down
Anything involving Terra from FFVI. /sigh....ahhhh...
Lightning from FFXIII because she is SO FREAKING INTENSE!!!!!
...or Goodwone, Sandric, Mcfierce, Shadowbill, Tots, Kristeen, Pneumatikos, Kutluch, Pianoforte, and Samboe staring down The Lich King with our weapons drawn, looking awesomer than can be imagined.
