All the fanatic 3d modelers or texturers do take a peak over at the battles>contest.
The idea is to creat a landscape wich has the next thing s in it:
1.a sky(overday)
2.ground, a realistic looking ground may be created with textures offcourse
3.objects such as trees building signs well everything you can think of
But it has one limitation:: you may not make a city out of it it must clearly not be a city.
For the rest have fun, hope you can create something nice!!
O, if those beautifull pics are done post the over
