Mugello landscape shots (For Davide)

I have asked Davide two weeks to enhance some points of his gorgeous job, and I´m trying my best here, on these topics:

1. Improve some textures based on real pictures (kerbs, trees, horizon)
2. Improve some of the 3d landscape, mainly hills and inner land;
3. Create new 3d Bridges for main straight;
4. Create new podium;
5. Improve banks with some 3d making;

I´m not sure now if two weeks are enough. But Please, Davide, it won´t hurt!
