Hey there! Welcome to the guild!

I have two things I would like to point out on this map. First, the rivers. We have people here who are part of what's called the River Police. I was surprised by this when I joined not too long ago. It turns out rivers have very specific and predictable ways of flowing, and tend to follow certain 'rules' as a result. An easy to understand explanation on this can be found in this tutorial.

The second thing I would point out is that the edges of your continent seem very smooth, almost round. There are several tutorials on how to do this differently on this website, though it depends on what you're using to design this. What program are you using?

Aside from those things, I think it's a good start. Hope to see more from you on here!
