looking for some ideas

[torikoos]

Kevin,

apart from giving your terrain some slight variations in height (even flat lands, are not always completely flat, and even if this is the case in some areas, a model tends to look a bit more 'real' with some slight variations) , but also be aware that you are better off using a variety of ground foams and other materials.

Just foam of one size and colour will look odd, mix in a few other colours that are related to your main colour, also use some that are slightly finer and coarser and mix these in randomly, and then finally use some grasses (static grass, or cut out pieces of grass matts (again in various related colours), and shrubs and small bushes will make it look a lot nicer.

If you're not sure, try it on a test area, and see how it looks, but variety in particularly texture and colour, aswell as size are key to a realistic landscape.

Let us know how you get on.

Cheers, Koos

PS: I nearly forgot, bright colours are usually a bad idea too, better results are generally acchieved by toned down colours, autumn and late summer blends etc).
