I think I finally found the masterwork symbol I am going to keep (first row last column). Round like a turtle, spindly like a web, and blocky like some coal/rough gems. I like it. I changed the '@' (fifth row first column) to be the simple faceless guy from
Lord Dullard's Tileset.
Made changes to the Metal Veins which I think are more appropriate. But I can't vouch for their appearance. At least now they veins appear to flow into the rocks next to them. (Tenth row down, forth one from the right next to the new lobster/yen sign)
Made the rope reed look like reeds but made them connected so that they would look like 3 prongs to a splint. Not very apparent but I think a little better than the weird 'f'. (Tenth row last column)
I have never had the experience of coming across a roc nest... but I made one anyway. I don't know what it looks like in game... but I think it is more suitable that the 1/4th symbol
(11th row 4th from the right)
I am struggling with the instrument. (11th row 8th from the right next to the cloth bolt). It (sorta) looks like a guitar... which isn't even one of the instruments in the game! I don't know what to do about it. Anyone have any examples of a 12x12 harp?
Table is updated and looks nice. I am probably going to change the chair, still doesn't look quite right.
Fish looks like a fish/leg of lamb/chicken/llama/etc.
I changed the weight symbol to some sort of palm tree. I hope it looks okay. (second row from the bottom 3rd column)
Crown/Ruined city looks much better in my humble opinion. Though feel free to tell me otherwise.
Changed the sapling symbol to look more like a plant.
I think the pot looks 'okay' in the mediocre sense. So it will have to do for now. Not sure what to do with the large pot/bowyer symbol.
Changed the weapon rack. If you don't think it looks right please let me know and I'll change it to two arrows intersecting. Maybe a shield-like thing in between... I don't know. It is supposed to be a hammer now. (Bottom, forth one from the right)
Changed the blocks/minecart so that they look more appropriate. Though both will look funny on the trade depot (along with the table, chair, wooden doors, and any other item that has black space around it) but due to circumstances I think I am okay with that.
I would have posted pictures but a lot of the changes I made were on someone else's computer.
