Initial comments on the cities, from east Asia to the Americas, moving westward:
Japan
Sapporo was not founded until 1868. Japan had little presence in Hokkaido until the very tail end of the Tokugawa shogunate, in the 19th century. Hokkaido should probably not be settled in 1700 (or perhaps have an independent or barbarian city).
Korea
All looks good.
China
Changchun was not founded until 1800. I'm also concerned that its presence would make Russia settling far eastern Siberia unlikely. It should probably not exist. Otherwise, I like the way China is set up a lot.
On a related note, I assume you meant Tashkent to be Urumqi. Either way, it should probably be barbarian rather than independent (so it has immediate conflict with China).
SE Asia
All looks good.
India
Mostly looks good. I'm a little concerned by the inclusion of Goa, though. The Portuguese were not serious players in India after their 1664 loss of most of their territories there to the Dutch. Although they did still hold Goa, it wasn't very important, and I worry that the Portuguese could have too much influence in India. I would replace it with Dutch Cochin, as Anglo-Dutch conflicts in India were very important in the 18th century. That would also allow you to add a Mughal (or independent, but in 1700 Mysore was a vassal of the Mughals) Bengaluru to have more Mughal presence in south India.
Iran
Looks good. I assume you'll have Iran immediately respawn in 1700?
Turkey
Is Bengazi really necessary? It's an awful city site. Also would include el-Uqsur in Egypt.
Russia
I think Tomsk is really out of place, though it's hard to tell. Otherwise good.
Poland
Warsaw was the capital of Poland from 1596 onward and should be the capital here.
Austria
Is it feasible to give them Budapest on the Oil? One city seems too weak for the RL quite powerful Austrian Empire in 1700.
Prussia
Ugh. Frankfurt and Hamburg should be independent.
Scandinavia
Interesting choice to have only Sweden, but it makes sense. Too bad there's not enough room for Riga on this map, but if you do stretch the map one tile, I'd try to fit Warsaw (Polish), Konigsberg (Prussian) and Riga (Swedish) all there in a stack.
Italy
Solid. I think Venice is better than Milan, but up to you.
France
Fine.
England
Fine.
Spain
A Coruna should be one tile west (on the NW tip of Iberia). Otherwise it competes too much with Bordeaux, and it's on the Atlantic coast, anyway, not the Bay of Biscay.
Africa generally
I think Timbuktu should be in as an independent (with an expired-for-almost-everyone University of Sankore). Almost certainly more important than Ngazargamu (not Ngazargana). I think Ngazargamu should be 1E, but that's hard to judge. Otherwise good.
South America
Mostly looks good. Not sure French Guiana was terribly important back then, so it could maybe be omitted. Also would be great to represent Potosi, and this is the best opportunity.
Central America
To make up for omitting Cayenne, maybe you could give the French Port-au-Prince instead of Spanish Santo Domingo. I also think the Spanish need somewhere south of Belize represented, maybe Cuidad de Guatemala. On that note, Belize was pretty insignificant in 1700 (and at all other times), so it could probably be omitted.
North America
Charleston is too far south. The swamp north of it is supposed to represent the
Okefenokee Swamp, which is in southern Georgia. (Personally, I think the swamp tile should be changed to a hill, but if you're keeping it...) Either way, Charleston should be on the Deer.
The lack of any representation of New France is incredibly problematic, though it does crowd Boston. It may be that the map in that area needs to be reworked to better fit in both Boston and Montreal. Boston is too far north as it stands anyway. Toronto was not founded until 1793 and should not be included. The British did not control modern Ontario until 1763; it was French in 1700.
By contrast, I think including British Halifax would be a good idea.
