Those portrait rips are just what I was hoping for! (Damn I love the Genya Arikado portraits, they're so good!)
I feel like these ones cover pretty much the remaining portraits, and also give us different views into each character, which we could rework into other portraits to have a bit of variety, while keeping everything in the same artstyle.
For example, for Charlotte, we can use the 2nd one (side view) in that rip for her text portrait, and work with the other 3 for other portraits. The same applies for Jonathan's.
@JohannGralog, what do you think of these?
