I think you managed something I always struggled with. When adding raised mountains the landmass always ended up looking too small. That doesn't happen here. The land looks big, maybe cause of all the placenames you added.

Some of the mountains are better than others, I would try to figure out which one works for you and work from that.

In general I see many people on here lable their maps directly on the drawing, I would reccomend to do this seperatly and combine it in photoshop. Partly because writing and drawing (atleast to me) are different skills and im better at drawing than lettering. And partly cause its so much easier moving thing around and changing things after the drawing is finished.
Keep up the good work.
