I'm also confused about the map projection - but that aside, it looks good so far.
I think the most important question to ask yourself is: what advantage does this map offer over every other huge world map we have?
What is it that makes your map special, or different? What do you hope will make people choose your map over the others?
Will it be more detailed (and if so, how will you manage to get more territories in the size limit)?
Will it be more balanced (and if so, how will you achieve that)?
Will it have better art work, more strategic functions (wastelands, sea territories, bottlenecks) or an interesting new system?
If a player has to choose between your map and others such as https://www.warzone.com/Map/19039-World-13k
- what is it that makes yours better?
It can really help with the map making if you know your answer to that question!
