Lovely artillery pieces.
My main gripe with this map is the lack of a northern convoy route from UK to Russia via the white sea. This seems like too vital an area to be missing.
Be aware that the geographical terms terms “Upper” and “Lower” refer to altitude, not latitude; e.g. Upper Bavaria is south of Lower Bavaria, Netherlands and Belgium are referred to as the “Low Countries” despite their northern latitude.
Baghdad is too far north. This tt should be Kurdistan/Mosul; Kurdistan should be Cappadoccia.
Belorussia and White Russia are the same thing.
Some tt names seem odd; why not East and West Ukraine rather than “Kiev”?
Kosovo in wrong place.
Borders given for Poland and Baltic states really date from 1918.
You’ve started with Moscow as capital; I’d have used Petrograd but allowed Russia to move the capital once in the game.
Bukovina was ruled by Austria rather than Hungary, so should be part of Galicia rather than East Hungary.

Rome is in Latium.
