The City of Shiel

[Ascension]

I think the fields are too regimented, looks sort of like Tetris. I'd make them free-form with wiggly edges and thick/thin parts, big fields and little fields, and use hedgerows to separate the fields and also roads. But to keep it in style with the city itself I'd also reduce the color. As for the river, it looks like a canal - chiseled in, it has no banks. I'd reduce the color on that as well and use the Dodge tool (or white or light blue) to put in some color variations so that it's not so flat. Here are two maps that I refer when doing something in this style. Your goal may be different but these may give you some ideas.
