Being honest, as a pretty popular mapper, this map is awful, i'm not telling you to stop, but don't release maps until you have made atleast two or three working ones you will actually try to IMPROVE ON instead of making it and leaving it.
There's far too much brown dirt, if it was ice/snow, it would be covered, so choose another texture or make your own.
And it's too sharp to be a mountain, you just abused the lift terrain tool and called it a map, what's the motivation in building here? i don't want to build particulary ANYWHERE in the map, it's either too flat or too jagged.
