Hello here, i'm working on something huge to help modding community and i'm looking for a modder and pixel art artist to discuss and help me to finalize some little things before releasing my tool.
I'm actually working on an app to help people to create mod content for SDV, it's scan your game folder to import vanilla and custom content (Maps, Assets, NPC, items, events, custom commands, schedule etc...) and help you to create scenes with wokflow and timeline system. It detect conflicts between mods too. You can add custom NPC (with their own spritesheets and you can build custom animations), items, portraits, etc...
This is a preview of my app, i made that video when i'm testing the choice system in live.

There is already a SDV Portrait maker made by the community, you could try to ask for their permission to reuse their work? Or alternatively, knowing this exist, simply redirecting people to their website and letting them make portraits there
(Just curious)











it's not entirely clear in the code either, but those are the constant numbers for skills elsewhere
