Hi Dain, looks like a good beginning you got there... and lot of work left too. The land seems to be hoovering over the river so I would remove the drop shadow. Concerning scale, its always a question of the region size - take a real life example and use that for comparison. If an A4 printer is what your have access to, then there is no need to go bigger than you did (unless you wanna print on several pieces of paper). When I choose the scale for my Mountain Realms I was thinking about how long it should take to travel from one side of the map to the other - and then calculated backwards with 50 miles/day on horseback as a scale. In the city Breakwater I'm working on now I began with one scale - then after having placed a lot of buildings - I scaled down, and now I'm thinking about scaling down some more... I'm concidering how big my houses are and recalculating after that.
So scale is always tricky, and you are allowed to cheat - and if a player calls you on it - SMITE HIM! *lol*
