Thanks for the feedback! Your english was good.
To be honest, I don’t really like the FE1 art either. I just used it because I knew it would be easy for a single person with minimal portrait skills to implement. I was thinking about using the repository for art, but portraits were missing for about half of the characters.
I also thought about using FE3 portraits, but some characters were completely cut (Riff, Darros, etc.) or never existed in the first place (Norne, Frey, etc.) I think that ‘Biraku Emblem’ has art for these characters, but I only learned about this when all of my portraits were already finished and implemented.
I might go back and change the art in a future update when I have time, but for now I’m just glad that the game is completely playable.
