Unconventional Map Orientation?
I'm working on a map using isometric mountains, forests, etc.
There is a mountain range running along the southern border of the region I'm working on, which means that the Iso mountains will take up extra space on my map. I would like to use that space for more rivers, structures, and population centers.
Would it be completely taboo to have South be towards the top of my map so that I will be able to have a better view of the region I'm working on?
Or, perhaps, since I'm using Iso mountains, it would look best to have South be to the right or left.
What I'm worried about is whether or not this would be too disconcerting for the map reader. For instance, the mountains would be pointing down if the map was held with north "up".
I'd love to have some input from the more experienced guys.
