Farmer portraits are not working

[W1ll0w]

Hello,
I downloaded SMAPI and a few mods for the game but the only one that is currently running without issues is the slightly cuter seasonal npc portrait one.
I really would like the seasonal farmer portrait one to work as well but I don't know what I am doing wrong. I already read up on the existing threads to this subject but nothing seemed to help in my case. This is the first time that I am trying to mod a game and I feel like I don't know what I am doing so I would need explanations as if I was five years old for this subject.

I am playing on Android and downloaded the latest version from the play store.

Sorry for my bad English, it's not my first language.

Here is the code and the folder in which the seasonal portraits are with their names

I would be very thankful if someone could help me 🥹
Let me know if you need anything else like error log
