I think I'm going to have quite a bit of feedback for you here in the next while. :P In regards to the mountains, my idea was to have a continuous spine of mountains, rather than occasional protrusions. I'm done quite a bit of my map, and I love how it's looking, so I'll share it here when I have more to show.
I might just edit a list of stuff I would like to see here, or things I haven't found, and continue adding as I get more ideas.
Things I have not found / would like to see:
- Large city components
- Farm lands
- Docks/port city
- Continuous mountain areas
- Continuous forest areas
- Continuous walls
- Stone walls
- Bridges?
- Winter Fjord 100% water tile
- Mountains without background
