Uhhm well… I’ve been to cities like London and Amsterdam a couple of times and while I thought I’d aim to take inspiration from them - to have some sort of general “old Europe” aesthetic for Santa Luison - honestly I’m not doing nearly as much research on architecture as I should!
I mostly just ass-pull the buildings I need to draw (so they’re consistent with the plot & action) and I’m obviously subconsciously influenced by Helsinki since that’s where I hang out the most. Helsinki doesn’t have all that much old architecture so it sucks as a reference though
But I think I’ll put more effort to the environments once they become more directly relevant to the story? Right now there’s more focus on character-building than world-building, but I aim to make it more balanced eventually. That said I wish I’d have put a little more thought into Cypress HQ since I’ll be drawing it in almost every chapter. It’s not quite big enough, for one thing :-D
