Hello fellows and good day!

I'm a little new to making maps with any amount of detail in regards to forests, mountains, coastlines and the like. I'm trying to step up my game per-say and was hoping to get some advice on a map that I am currently making on canvas for a very large D&D campaign that I am DMing. So far I have Gothwynn the dwarven state of the Confederacy of Darton finished (that is to say the base line work). I know there are some glaring mistakes pretty much everywhere but anything you guys can give me in regards to advice or feedback of any kind would be most helpful.
