PokéQuest Icons is a resourcepack made for both Journeymap and Xaero's Minimap/World Map and features hand drawn pixel art icons mixing the icon style from Pokémon Quest and the Vanilla mob icons that already exist within the aforementioned mods.
As of right now the pack is currently under development and does not have all or even most icons completed. I plan to have the first official release come along with icons for all Gen 1 Pokémon and any variants or evolutions added in later games.
You can keep up with my progress or vote on different designs for icons on the official Cobblemon Discord.
The most recent sample packs will be available here, featuring all currently completed icons as well as some alternate options if you know where to look.
