Hey together,

i started a big map project and expanded what was once a continental map (the southern continent) to a world map. I got a bit too ambitious and began thinking about correct plate tectonics and climatic influences.
The system needs to make the southern continent work somehow, the northern part is not so important/open to changes. All i know is, that i want a big desert there. The northwestern round patch is a dried out, partly dammed sea (was once a comet impact crater, the poor little, world was kinda shot at a lot in its younger days - could alos explain some out of place mountains).
There is magic in the world, so i can handwave some things ... but I don`t want to rely on that too much.

Here is the tectonic map i did so far:

I would be really grateful if some people who have less dangerous half-knowledge about these things took a look at it and gave some tips.
