Post skins you would like to see implemented on heroes. Anything goes. Just let your imagination run wild.
Torb: Garden Gnome Skin
Road Hog: Piggy Bank Skin. Roadhog with a top hat, monocle, suit, and his hook is a cane. He sniffs a wad of money to heal.
JoJo’s Bizarre Adventure skins:
Muhammad Avdol skin for Doom Fist
Hol Horse Skin for McCree
Mariah Skin for Symmetra
Halloween Lucio: Baron Cimetiere
Dystopian Riot Police Brigitte
Ancient temple statue Zen
Centaur Orisa
Wasteland Junker Moira
Casual Brigitte, or well more casual/formal/beachwear skins in general
Catwoman Widowmaker or Tracer. I feel it would fit both of them rather well.
I’m a little biased

Pajama Skins…we got Mei covered…lets get the rest of these characters suited down to sleepy time. And when you release this…introduce the “Pillow Fight Mode” in arcade.
Spider Orisa for Halloween? OMG Yes plz 
Johanna skin for Brig! 
John Wick McCree. I know Fortnite has “the Reaper” which is Wick in everything but name, alas McCree already looks like him and giving him a formal look would be interesting, which leads me to the next suggestion…
Formal looks across the board - After 2 years, I think everyone would like to see more normal looking skins for characters. Hanzo and Doomfist are the only ones to have them thus far, so maybe it’s time to see most of the cast gets slick looking.
More Outlandish skins - To parallel my sentiments of formal skins, I like it when OW goes overboard with a skin. They may not be the most the most appealing looking (like Cytorb for example), though I do give credit for the artist going all out over a character than simply staying safe. Orisa’s current Forest Spirit is an excellent example of outlandish looks. Reaper’s Pumpkin skin is another, Zenyatta’s Cultist, Torbjorn’s Magni, Sombra’s Rime, Ana’s Snow Owl, etc. You stuff that play safe.
Waiting on a beach skin for Tracer, Palpatine/Darth Sidious skin for Moira (or just a straight up Star Wars event), and maybe an event on “The Great Wars” each character has a skin respectfully for thier countries during both World Wars.
