Great work flo.
Some comments:
1. Flax is still distinctly photorealistic, even if you dimmed it a bit.
However, as there is no big problem with the current flax, we can just keep that one if you don't find anything better.
2. Your new papyri is great.
2. As is your new Stone.
2. Your new (bees)wax is great, though I think a slightly more zoomed in version would be better (if the resolution of your source is good enough).
3. Your new Ceramics is great
3. Your new fish is much better than anything I've seen before, but I think it's a bit too zoomed in. Is it possible to zoom out a bit?
3. I like the last two of your fruit suggestions.
3. Your timber is still a bit to light, but the new suggestion works.
4. New cotton is great.
4. Your grain is a bit too plain, and what details there is is too photorealistic, but it's still better than the current card.
4. Your oil is still too yellow, and the texture looks more like melting butter on a vertical surface than oil in a bowl. I'm thinking using the current image and making it more yellow would be better. This is a first try:


4. You sugar feels to grey, and looking closely it's too photorealistic.
5. New textiles is great.
5. New wine looks great, perhaps a touch to dark, but nothing major.
6. New bronze is much better. Still a bit "dull", but it's the correct colour now.
7. The new incense is great.
7. As is the new jade
8. New dye is much better.
So now my lists are as follows.

Bone

Iron
Tin

Still needing a remake (or decision on current options):
Ochre (but current could do)
Fish
Fruit
Grain
Oil (see above for proposals)
Sugar
Silver
Resin
Spice
Gemstones
Marble
Amber (but current could do)
Gold (but your amber proposal could do)
