This is the first resource pack I've followed through with and it replaces some of the vanilla Minecraft paintings with pixel art of my own. There are currently 8 new paintings in total:

The paintings used in the pack are taken from an unpublished mod I'm currently working on, LichTweaks (though this name will likely change). The mod itself is only covering surface-level modifications, but it's all well-documented and sets a good foundation for content expansion, and when it reaches a public release. The first looks at the mod will be found on my GitHub before anywhere else, though forge will likely follow soon after. I'm a student currently attending university so everything is definitely a WIP I will be pursuing progressively as I finish up my schooling. In the meantime, I hope you enjoy these paintings, I appreciate you checking them out!
Note: I have only tested this pack on 1.19.3, so I can't say for sure if it'll work on early versions.
Thanks,
LICHPUNK
