Even considering what a description of someone really sounds like, these example dwarfs do still seem kind of... stereotyped.
Maybe the adjectives should all be toned down in general. So things that are currently 'somewhat' aren't worth remarking on, and the new minimum variation is described as 'slightly'. Then still use mild qualifiers like 'fairly' further up the scale.
Or, might it be possible that you could choose the level of description you wanted in the init file? So you could change the parameters to [SHOW_BRIEF] or something, and go from Fugly Fortress to Functional Fortress once you had too many dwarves to make it worthwhile.
And on that note, I do agree that at a certain population point, most players will simply never look at any appearances. The ones for whom it'll be really worthwhile is the hermit or seven-dwarf players, or those whose fortress revolves around a single Morul.
Also, it would be cool if the appearances are linked to the attributes enough that number 9, "strapped with massive amounts of muscle and lard", gets strapped with only muscle as he gets stronger or only lard if his constitution/metabolism changes.
...Can dwarfs lose weight? Or is number 9 permanently a barrel body without recourse to slimmercising? Doomed to sit in a corner spooning sweetened kitten fat into his maw and cutting the angular runes 'FAT DWARF' into his body with a +steel razorblade+?
EDIT: Also, number 10 (Bembul) especially likes the colour of her own skin. I find this... worrying.
