Went to check sources. Here's what i found and fixed:
Several issues with misalignment, when tile drawing continues through the tile border:
— tiles 16 and 17
— tiles 219-223 (especially 221)
Leftovers and artifacts. Not sure it was intended to be like this:
— missing 4-pixel squares in tiles 176 and 177 (and also some strange artefacts in 176). If it was an attempt to make bordered tiles, then it's ok, but it wasn't obvious for me.
— tiles 219-223
— 244. There is no integral sign in DF, so you don't need to keep its upper part plain
I added halftone here and realigned it
— tile 254 (a.k.a. block, although i'm not sure it is an issue)
— missing shadow in tile 93 (])
— shading fills in \ and / are not the same. Not fixed it, don't know which one you consider correct
— there may be more tiles with missing or incomplete shading
And now to suggestions:
— Not sure that you need special X here. Conventional one works pretty well too (added in my revision)
— ó is used for text entry too, so be careful with it
(added in my revision)
— something wrong with Σ, it looks bolder than it should be
— Bars tile (240) logically looks like Bin, when it is near to barrel (i mean there is same three lines, just in square shape); not sure that's issue, though
— Maybe old militants were better, than new ones
— Last, but not least: I've added 'tile magic' to floor, so black background of items on engraved floor will be less distinguishable. At the same time i think walls are 'ok' as they are now
Points of interest: hatch fills, floor, bin, activated lever, Depot tiles
here is my revision:
Also + for adding halftone to bed tile and changing stockpile, it looks 100% better
That's nice tileset, keep it goin'
