This isn't going to be me suggesting anything gameplay related to Maxwell's rework, as we have many different threads for that. Instead I am going to suggest the concepts for the skins that are released with his rework. Every one of the original twelve survivors received a character skin and three belonging skins that were themed with their new skin (except Winona who got two belonging skins and one profile background). So following that idea, I conceptualized two possible skin sets for Maxwell:
The Magician Set
The Great Maxwell Set
The Magician Set:
Magician Maxwell (For some reason every time I drew this, it ended up looking like the Godfather)
Card Deck Umbra (Codex Umbra skin, both idle and active)
Magic Hat Bunny Hutch
Flower Wand (Clean Sweeper)
(if it isn't obvious, this is one of those wands that turns into a bouquet of flowers)
The Great Maxwell Set:
The Great Maxwell (Excuse my poor art skills. This is the Maxwell from Chapter 5 of Adventure Mode of the original DS)
Shadow Throne Saddle (War Saddle skin)
Repurposed Wooden Thing (Shadow Manipulator, both idle and active)
Shadow Wilson Worker (Probably the easiest skin to implement. Shown is the logger, but ideally there would be a miner, digger, and duelist too)
This is a nod to that Shadow Wilson with an axe that was always teased from single player (and the blind box figure), but never actually implemented. This also could be explained that Maxwell and Wilson are still bantering, and this is a jab at Wilson since Maxwell likes the idea of telling Wilson what to do. Wilson could also give a jab back at Maxwell when his rework comes out with this gross caricature of Maxwell in the form of a Meat Effigy:
Let me know which set you like better, and if you think that they would fit in the game. Excuse my poor artwork, this is more of a concept which essentially is my way of excusing my lack of artistic abilities lol.
