I can't respond to everything that's been posted lately, but I'll touch on a few things:
@Jarathor: Those dwarves are great! I like using subtle color and tool differences to differentiate their job a bit better than distinctive hats. Care to take a stab at female dwarves? Tolkein aside, I'd prefer them beardless; Toady made them beardless with the cosmetic layer update anyway.
@Seuss: Fantastic work on the crops; very shiny! Judging by the name, the Pig Tail has a thick curled stalk, but before I knew what it was, it looked like there were three red leaves hanging off it instead. You might try making the stalk a bit thinner, and letting a bit of the far side of the curled stalk show through, probably in the middle to avoid confusion. Also, as Impaler mentioned, seeds and withered plants would be nice to have. Granted, once you think about Surface Plants, Trees, etc. there are a lot of Dead saplings/shrubs to consider.
Took a look at the list, and I'll take a shot at updating the web list with the information, as well as tiles that are done now.
@7¢ Nickle: Death to Honkey Fantasy indeed! Totally digging the humans, especially that diplomat. Depending on how the GFX get standardized, they might need to be color balanced to match the high-saturation style of some of the more recent tiles, but they are fantastic.
@Pubby: That is several kinds of fantastic. Legolord would be so geeked.
I'm going to do my best to start compiling the graphics into the list, and update it as per Seuss' list, so we can see what we have done so far, and start to come to a style consensus.
