I remember Korean Peninsula as norther than Japan and sharing borders with Russia, Taiwan being a bit further off the mainland than in your map and Papua/New Guinea as just New Guinea being a whole-White anglo country like New Zealand and owning the entirety of the island instead of sharing it with Indonesian kebabs, btw kebabs were small barely significant minorities everywhere eastern of Bangladesh.
New Zealand seems at the right position in your map.
What else I remember from my home universe's map.
Mexico was smaller and the entirety of the California Peninsula belonged to the US.
Cuba was much bigger, even compared to Haiti/Dominican Rep (two close but separated islands, with Hispaniola being the one with the Dominican Republic and couple of other smaller sovereign countries).
Brazil was significantly smaller and its part eastern of Paraguay belonged to Argentina (that I also remember smaller or at least less elongated). Uruguay existed but can't remember where exactly. Its coastal and that much southern placement seems wrong. Las Malvinas were visible in the map and closer to Argentina, they were of Hispanophone majority and the Brits were only an elite significant minority. Also British interventionism was almost universally condemned by the international community as imperialist except from the US and certain Western countries arguing that it was a necessary evil against Argentina's "fascist regime".
inb4: Argie Argentina was not definitely not White in my universe except for its influential "dictator"'s close circle who was a personality of similar caliber and also somewhat of an ally to the contemporary Pinochet but without the CIA-support accusations
Many islands in the Western Pacific were visible at that scale. Russia had many northern islands but most of them were much much smaller and closer to the mainland than that map.
Canada had no islands that far up north, and certainly had no island that big and as far up north to be in any way comparable to fucking Greenland, they barely reached norther than Alaska. Also don't remember that huge long line of Islands southwestern of Alaska.
Iceland was much smaller than yours, maybe even smaller, than current universe's one and closer to Europe.
Gibraltar and Suez were as in current universe but Sicily was certainly much further apart from Africa just like in your map and the Red Sea was open on the southern border like in your map.
Your map's Canary Islands seem just fine, maybe they should be a tad bit closer to Europe.
You fixed Madagascar think it was Magadaskar in my universe but I might remember it wrong due to convenience of calling it Magadaskar in my mother tongue (you might have put it a bit too close though) which was also heavily colonized by Whites of mixed French, Anglo, Dutch and mullato population and there were zero historical influences of Islam or Arabs in it.
There was no majority Muslim country in subsaharan Africa other than Sudan (that was much smaller and confined to its southwesternmost reaches) and a much much more secular Somalia. Ethiopia and Eritrea were 85+% Christian and Somalia had a significant majority of Christians. Nigeria was about 50/50 Christian/Muslim with Christians most likely being the plurality.
Israel occupied all of Palestinian peninsula and Egypt had only control of a small strip of land east of Suez as an outcome of the 7 days war. The Dead Sea was (barely) visible at that scale.
