World with no name yet - comments and tips wanted!

[Dewati]

So, I've started a new project for a world that I want to use for my writing and possibly roleplaying. I just found this forum and I must say that you guys have inspired me so much to go way more scientific than I was planning on However I will probably not go all the way with that, I also really want to start writing at some point haha...

With that being said I would love to get some comments on my work along the way! This is the map of all the land masses of the world, though there might be more water and ice outside the boundaries of the paper. I'm also using this project as a way to learn how to draw better so please be gentle about the drawing itself (though tips are welcome!).

I've also drawn up my idea of the tectonic plates. What do you think of those? Any general thought of how the climates would be affected? For example the big mountains on the eastern continent will probably impact the climates on the north and south side of it pretty much.
