We could still use a scroll item icon, as the asian bookshelf is a scroll shelf. As for the shelf itself, I like them but i think it'd look better with the scrolls visible straight-on instead of an angle (it feels like they should be jutting out 3-dimensionally with the angle they have, but it doesn't really even provide that illusion.) and perhaps more detail like the other shelves, like little bonsai trees, ect. The jukebox could be some kind of Chinese/Japanese/Korean instrument, leaning against the block kind of like the violin option. Somebody mentioned a cho-ko-nu crossbow earlier, and I liked the idea, but maybe that in addition to a more standard-looking bow, like a mongol shortbow?
Since katanas were exclusively Japanese as far as I know, for the sake of making the pack more "open" as far as asian themes go, maybe a selection of Chinese-style swords, with a bronze sword instead of stone? I know someone with more knowledge of asian history will probably correct me, but I believe bronze continued to be used in abundance in Chinese warfare even after the end of their "Bronze age," and the brittleness of bronze compared to iron would make sense as the stone sword vs. iron sword durability.
That, and it would look cool XD
For building material, maybe a different stone brick? With all due respect, it doesnt look/feel like stone brick, resembling more some kind of cobblestone instead. It probably looks good in certain patterns or builds, but if someone has a pre-existing castle or something it wont look great with that particular arch-y pattern repeated over and over.
Is that what you're looking for as far as suggestions go? Ps, cool progress on prehistoric
