Hi there! I’m a noob too, but I’m excited to be able to actually help with something ;D
The community repo is here: https://drive.google.com/drive/folders/1jiiTpNXgAlr4lZBh8d-nJFdO-Jus5VXV and you can find the F2U mugs under Graphics/Portraits. They’re organized by game and by creator, and it seems to be updated very frequently!
For making maps, I use FE Map Creator, which I find very accessible, but I’m sure there’s other tools out there too.
Have fun!
