I do recommend changing the urban polygons such that either the hex either is fully urban or not urban at all, and not use small fragments of urban area. Even small fragments will lead to hexes being tagged as urban, and my tool renders them as urban.
Built up terrain is so different from other terrain in how it affects combat / tactics, that you want the map as clear as possible about what is built up and what isn't.
Mad Russian (Steve) did a great job coming up with crisp and clear maps in Red Storm (we might have changed the looks a bit, but we sure stuck to his formula).
The only thing I do break into fragments and combine with (fields) hexes is forest, just to better resemble the forest outline.
There is a minor issue with obstacle id's at the top of the maps.
