These look great, and it’s awesome to see them working in-game!
Are the ore barrels planned to be a decoration, or a storage item? IMO we could really use an “ore pile” item to condense the large amount of ores you get when mining veins into a more manageable single item; they can then be harvested as the blacksmiths need more ore. Hopefully you can copy/paste most of the required data straight out of the stone/clay/log piles for that.
Also, in line with what @8BitCrab mentioned with the very “voxel-y” ore in the barrels, what if you had a flat base of that style to “fill up” the bins and then scattered some of the smaller ore items over the top, so it looks like there’s a lot of ore rocks packed into the barrel? That way, it would create a visual link between the barrel and the ore rocks it’s storing, and it would be a way to carry the ore rocks themselves into your model while also keeping your own work, so there’s a nice mix of textures and it’s not simply a copy/paste.
