Here's a link to some of my older maps.

I need to generate terrain that scales to 1-50km. Wilbur and FT seem more suitable for larger areas. We mainly fight in a 1-5km area but I can see us maneuvering in 20-50 km areas once we scale the game to company level. I typically create maps where 1px = 1m. My biggest sticking point used to be my trees or forest areas but I'm fairly satisfied with my current technique. I want to improve my hills and make them look more natural. I've been experimenting with randomly generated elevations using the clouds filter but I keep getting the same effect as Wilbur or FT. Looks good for larger scale maps but not so good for my scale. One of my requirements is to show elevation lines which is why the hills in my screenshots look like multi-layered cakes. I'd like to smooth out that stair-step look and achieve smoother transition between elevations. The other problem with my hills is the base layer doesn't look very natural, it doesn't buildup naturally.
