Alright I'm planning to do a redo soon, thinking of someone to do. I already have a few in mind and did some concept art of tons of different characters at work and doing a small amount of writing. Now its just polishing.
Which would you guys like to see coming up?
-Mammon
-Vaggie
-Glitz/Glam
-Crimson
-Chaz
-Lute
-Adam
I'm still planning on doing them of course just going to focus on a more preferred character to finalize a design.
Also so far which do people like the most? I want to get a gadge of what others think sticks out on the character, and to hone in what makes a design pop out and or makes them demonically iconic. Standard stuff to work on with shape language of these characters. As I am making sure each one has something to differentiate from one another adding different body types, sizes, and making a prominent feature stick out.
Here are some ideas/ what I would do for each character:
Mammon - I saw someone mentioning that Mammon should have been a fat cat, and I can't disagree. Besides the obvious symbolism with Greed, I think you could get a lot of great expressions with a cat face and fits well with the emotive personality he has. Also, make sure he looks...well fat. At least in his first appearance, he looked like a skinny guy wearing a wide robe.
Vaggie - Since I've read you were keeping the "Vaggie was an Exorcist" for your redesign, main thing I would want is that she should look different from when she's still an Exorcist to when she's cast out to Hell. It annoyed me to death when she takes off her exorcist mask and the only thing that was changed was that her hair was short. Like why does Adam and Lute have regular skin tone and yellow eyes, but Vaggie has gray skin and pink sclera when she was in Heaven? If all Exorcists were created, wouldn't they look relatively the same as one another for uniformity? She should have a brighter, cleaner color pallete for when she was in Heaven, and then it becomes duller and greyed-out when she's in Hell to show a change in not just in her appearance but world-view. And her outfit; please be anything but "McDonald's manager uniform".
Glitz/Glam - I'd say something similar to their beatboard designs. They actually look more like clowns/jester (I say jester too because Mammon and Fizzaroli resemble jesters more than clowns, but I guess Viv can't tell the difference) than what we got in the actual show, and I assume they changed the designs because it's easier to animate.
Crimson - Similar to Glitz and Glam, look to the beatboard. He actually looks more like an intimidating mob boss here and not just another Moxxie. Plus we need more muscular men in these shows.

Chaz - My main issue with Chaz is his personality really. You think he's going to have more depth after the flashback Moxxie has of him, where the animation of Chaz showing his expression that he regrets leaving Moxxie behind like that to the cops. But no. He's just "haha horny and stupid". So, yeah, just fix his personality and have his design reflect on that.
Lute - I'm actually not too bothered with Lute's design. The worst that I can think of it is that it may be too basic? I remember when it was mentioned way back that a Sinner's form is more monstrous/animalistic/non-human depending on how bad their sin was when they were alive. So angels looking more like humans made sense to me. I feel like all the exorcist should look similar to each other when they have their masks off to show a soldier-like mentality and that they all have the same worldview.
Adam - Like Lute, I don't mind Adam's design. It's just that his personality doesn't scream "first ever man to exist and is over thousands of years old". (This is also just a problem with Viv's characters that the majority of them act like they're teens and/or young adults, even if they're over a millenia old.) Adam should have been a more mature, nuance character. At worst, he's jaded and stubborn in his ways. For as long as he knows, no soul from Hell has ever been redeemed to get to Heaven, so why should that change just because the princess of Hell believes to be the case? Maybe he himself doesn't want to exterminate the people in Hell since they are technically his children, part of his lineage, but he has to follow what the higher-ups tell him and that this is best for Heaven. Maybe he looks tired and gruff, like the pitch version when we just knew him as the General of the Exterminations.
Anyway, these are just suggestions and ideas that I had. You don't have to use any of them; they were just thoughts on how I would design these characters.
