Hey everyone!

I'm kinda working on a world map for an RP campaign I want to run in the future, but I want it to be somewhat realistic. So, I was hoping the experts over here could drop some hints!

This is what I currently have.

While I'm not learned in geography or anything of the sorts, I know mountains are made by fault lines and that the ocean currents determine the climates. As well as the fact that water usually originates from the mountains and heads back to the ocean, thus creating rivers.

Because of this, I started with plopping down my landmass and then doing my best to add tectonic plates (big black lines) and the ocean currents (small red ones). Any advice is welcome and feel free to scribble all over it to make a point

Thanks in advance!
