The map's coming along nicely but I've got a little suggestion. Your glaciers are a wonderful feature of the map but I think you could make them go into the little side valleys, not far but a little bit, it could help break their regularity (not too much but a little bit).

And a personal preference, do not hesitate to draw your coastal waves yourself, it looks better. If you stick with the automatic ones, after expanding or shrinking your selection, smooth it 1 or 2 px before drawing the line, it makes it less angular.

Keep up the good work !
