Great mountains

The villages are laid out in too regular a grid. Even if the distance between them varies, they are still essentially on a grid pattern, and this is reinforced by the grid pattern of the roads.

In reality the villages would be more scattered around than this, and the road network would be optimised rather than laid out, ie a compromise would be made between the best connectivity (often an almost pure grid as seen in big newish cities like New York which have been designed rather than grown) and a system which uses the least amount of road necessary to include all villages (this usually large roads running through the landscape connecting large settlements, with smaller roads connecting smaller settlements to the trunk roads). Either extreme looks artificial, but for a medieval landscape you definitely want to avoid the 'designed' look, unless the area's history says otherwise. Keep in mind that many of the villages would have sprung up along the roads between larger settlements, with more outlying villages being less densely packed. Add in variation for landscape features (even in the lowlands not all land is desirable or usable, for a multitude of reasons) and hopefully you can create a layout that looks evolved and lived-in rather than designed.

Unless of course your fluff decrees that the current inhabitants only arrived 50 years ago and their pantheon is ruled by a god of geometry, in which case ignore everything I said.


But apart from that minor point, a lovely map, and even just the scale of the thing is impressive
