- Finland shouldn't be separate from Sweden. Without Russia taking them over, the sense of Finland as separate from Sweden likely wouldn't develop, since while Russia tacitly encouraged this (as long as it didn't involve breaking with the Tsar altogether), Sweden would propagate the idea of Finland as an integral part of Sweden, and Finnish would go the way of, say, Welsh at best or Occitan at worst.
- The Church of Sweden is never,
ever going to agree to become Orthodox all of a sudden. Breaking with the Church, even if it was only a single peasant and his family doing it (as happens with Danjel in
The Emigrants), was considered heresy at best and treason at worst, and was punished by deportation. Most Church officials held the deep belief that Lutheranism was the only true form of Christianity, and no Archbishop of Uppsala would ever place the crown on a head that didn't follow it.
- As you say, the French aren't likely to invade Mexico ITTL; even if they did, I fail to see them actually
annexing the country. Even Napoleon III only wanted to put a loyal emperor in charge, and without his megalomaniac foreign meddling, the expedition is likely to stop at shelling Veracruz and extracting a promise to pay (IOTL, the Spanish and British pulled out at that point).
- There's no real need for Brazil to build a railway across the entire Amazon Basin; reasonably large ships (Wikipedia says 3,000-9,000 tonnes) can get as far upstream as Iquitos. After that, however, they do need to build rail across the Andes to Peru. Going to Trujillo or Chiclayo through Jaén seems like the best way of doing this.
- How do the British get to Canada if the French retain Louisiana
and Quebec? I'd think at least Ontario would be French, and for that matter, so should much of the Midwest. I'd think a Wabash-Maumee line would be a far more reasonable border for the New Netherlands, especially since rapid expansion wasn't their style (they were far more mercantilistic in their colonial dealings than either the British or the French, and would likely be content with OTL New Jersey and the Hudson valley).
- Sweden should go all the way to the Pacific, since Russia had trading posts all the way across before Poltava IOTL; for borders (in Siberia and generally) you should look at geographical lines; the
Stanovoi Mountains formed the border between Russia and China pre-Aigun IOTL, so they'd make sense as the TTL border. Unless, you know, you'd want Sweden to actually be able to use its coastline (Okhotsk isn't much to use in the winter).
- How does China do so well? Did they pull a Meiji?
- Same for the Mughals (which, by the way, would be awesome).
- Transvaal shouldn't be called that, since it holds land on both sides of the Vaal ITTL; the name Nieuw-Oranje makes a good deal more sense for them than it does for the state you call that, for which Zambezia might work.
- Borders in the Balkans are
way too convergent. Vojvodina, in particular, should be within Austria.
- Austria would never be able to colonise. They don't have sea access except to the Mediterranean, and the British control both outlets (I can't see Gibraltar, so that may be Spanish, but it's still not likely to be Austrian).
- Moving to Worlda would also do you good. If not otherwise, then because that map is rather ugly.
