Most of the cosplay stuff has prolly slowed down due to the quarantine. Most people made the cosplay for events and cons and just also sent pics in, but those aren't happening right now.
Liam mentioned this on twitter at some point, that there are so many good artists that it's hard for him to pick and choose. If it's a comic that's shown, the pages get their individual spots and such. There's a LOT more variety now than there was during campaign 1, at least.
