How about the four gentlemen sitting around the table playing the game, with Mr. Peterson opn the computer screen in the slight background. All 5 figures are contributing to a collective thought balloon of the final battle above their heads in the top third of the picture.
Wow that's some request, do you know how much work that would be ?
Generally I don't do portraits of real people, because I can't make it look right, also, If I were to draw a full battle scene, I'd draw a full battle scene and not "waist" it by stuffing it into a thought bubble.
Cool request though, but a bit beyond my skill level

And pretty much impossible to do in any case. Slappy must be a hoot trolling at conventions.
"Hey, Rob Liefeld! Can you draw a picture of Cable ski-jumping over Triptycon (but not the third season Transformers Triptycon, the version from the Japanese season five with the Headmasters) while Gambit makes out with Rogue and Bug-Eyed Earl from Red Meat has a gunfight with William Hartnell wearing his first doctor costume and a German World War II helmet while the Spirit of Vengeance from Jim Valentino's Guardians of the Galaxy run works the fryer at Sizzler while cleaning his excess earwax with a golf pencil?
And do it in purple crayon with your left hand? Sign it to Slappy!!!"
