So this was my first attempt at Vampireworld versions of Aziraphale and Crowley in my Bubbline AU, but I wasn't fully satisficed with it. I liked Az's Barbarian-Warrior-of-the-Wastelands aesthetic as a counterpart to Bonnie's Military Chic, but the Star didn't feel distinctive enough from Starcaline on both a design and implied characterization level.
So after a while for feeling low-key unsatisfied, I took a second go at it, I was trying to go with the idea that the original Vampireworld kinda 'inverts' Marceline and Bonnibel's aesthetics while also exaggerating them and letting them put own personal spin on things; Marceline's now the 'girly' one wearing a lot of pretty dresses, but in a darker color-scheme and a more gothy style and Bonnie's more practical clothing lean much harder into butch-ness then Mainworld Marceline even harder and, again, have a more millatry-vibe rather than Punk Rock.
So I tried to apply this idea to Crowley and Aziraphale by giving them designs that invert their usual color-schemes, while keeping Az's Wasteland Barbarian Aesthetic to make him looked 'old-fashioned', while Star!Crowley still has a sharp, modern look.
