Well my first concern is whether they look good or not I suppose. Essentially it's just just farmland for wheat/barley/oats.

What I would like to aim for is a landscape more like this. That is the end result of feudal open field ploughing over many years.

But I can live without that. So most importantly - do my fields look ok? (on a side note most of the unpainted stuff and a good portion of the periphery stuff will be cropped out when I attempt to use a more parchmenty background).
