Looking at Artmods map and the one Shades used I don't see allot of difference. How come it's twice as small?
I don't really understand what you're getting at. I only used official sources when constructing my map. The shape of the map is virtually the same as the Oblivion Tamriel map. Maybe a mile in TES lore is different than an Earth mile; I don't know.
We used different points for the Red Mountain, mine was nearer the base. And since the map I used didn't have Mournhold on it (must be a small town), I probably undershot the distance.
I find the miniscule land area disagreeable in either case.
