Nice first map so far Redireckt!

I agree with Azelor that the texture is pretty strong. I am not sure what software you are using but I'd consider lowering the opacity on the texture layer. Also, some parts of the texture kind of conflict with the land. I am thinking here of that island north of Inissat that has a crack straight across it. Consider using a layer mask to hide the texture areas you don't like over your landmass or consider having two textures: one for your land and one for your water. I really like the texture on some parts of the land though I must admit.

Be careful with how your rivers flow. They don't really cut up landmasses like the south west of Inissat is having done to it right now. They usually flow from many small streams into singular large rivers taking the path of least resistance. There are some great tutorials on this site somewhere I don't have time to find right now unfortunately!
