This Minecraft resourcepack adds some new paintings by using the CustomModelData feature added in 1.14.
It is inspired by the custom paintings used on the Hermitcraft server, as seen in this video (14:53).
Place the zip file inside the resourcepack folder in your Minecraft installation.
The following image shows the paintings available in the resourcepack. You can also add your own.

To get the paintings you have two options: using the give command or using mukitanuki's Custom Roleplay Data datapack.
Use the following command to give the player the custom painting defined by the CustomModelData number.
/give @p painting{CustomModelData:<number>}
Where <number> is the painting index as defined in painting.json
Alternatively, and more survival friendly, CurseForge user mukitanuki has created a datapack to change an items CustomModelData tag. You can download it from CurseForge.
Once installed you can run the command /trigger CustomModelData set <number> changing <number> for the index of the painting.
Check the CurseForge page for complete instructions on this datapack.
