Well, you've got a point here, but if I use a texture with more elements in it, the blending between textures won't be very nice looking...
The bad thing of a top-view game is that you have to choose the terrain texture very carefully. Even small inhomogeneities in the texture will be too obvious from the top view camera. Thanks for advice, anyway. I'll see what could be done here...
Adding some more vegetation, rocks, etc. could make the miracle. wink
