Posts from RTF is a global modification that replaces all towns in the game.

Indeed, the floor contrasts too much – the unnaturally perfect white tiles need some shade – perhaps a slightly grayish (or sandy-yellow) hue. There's a certain unnaturalness in the coloring, but the yellow domes, which add warm tones, certainly help. I'm not suggesting we smear the walls with dirt and mold :D, but in my opinion, a little more naturalness in the colors wouldn't hurt.

then you need to darken it so that the lighting doesn't turn the gray texture into white, or do something with the lighting (in general, it turned out well, and the criticism is just a tribute to perfectionism)

by the way, why is there a triquetra above the city? - I could associate this symbol with the League of Elements, with runes, but what do elementals have to do with it? - and the number three is not related to them in any way... or so it seems... :confused:
since this is a city of elementals, maybe a seven-pointed star would be more appropriate? (like 7 schools of magic), or a six-pointed star (hexagram) - there are only six elemental schools, the seventh school is not elemental (school of primordial magic)

Yeah, it's not very related. As an alternative, you could give them an Ankh, the symbol of mages from Might and Magic VII, or as you suggested, a star.

In my opinion, the icons don't quite fit the style of the game, but they are beautiful on their own.
Does it have a skill wheel? (I mean a graphical diagram, because it's not clear what and where the skills come from)
