First off I just want to say thanks Mike for this awesome graphic set. I've been using it for probably 2 or 3 years now and this is what Dwarf Fortress is to me.
I just started a new world generated with DFG32 (0.31.06) and thought I'd mention the following graphical anomolies:
- Rough Hewn Bituminous Coal walls look like gears.
- Stingray looks like a lever.
- Tigerfish looks like meat (drumstick).
- Milkfish also look like meat.
- Rough Hewn Conglomerate wall looks like a boulder.
- Rough Hewn Alabaster wall looks like a crown/traps.
I don't know how the graphics tilesets work in this game, so if there's nothing that can be done about these things,
please know that I'm mentioning these not to complain but rather in case you were unaware so they can be fixed, if possible.
Thanks again!
Anomalies like that have been around in the Mayday set for a while. I don't know if it's changed or not but for the longest magnetite looked like butterflies. I honestly don't know whether or not there can be anything done about some of them but based on all the changes in his newest set it sounds like he's trying to make it the least awkward looking as possible.
Some of the stuff you listed I think was done on purpose. Like the bituminous coal walls, I think he made them the gear/alternate gem shape to differentiate them from other gem walls. I would probably suggest changing the graphic to look more like a gem but I don't know what else might be using that graphic.
As for the rest, well fish should probably look like fish. I don't know much about editing raws but I think changing creature graphics isn't that big of a deal, not like tiles. Some creatures do use tile graphics so I don't know if that has anything to do with it.
In any case, making everything look right when you only have a limited number of tiles to work with can be a real challenge. That's why Mike has to double up on a lot of the graphics. There's tricks you can use to make them look different(see the capital X in the image file for a demonstration) but at the end of the day you're still left with just 256 tiles.
