Hello everyone and thanks for your suggestions!!
-
Australia: I've changed the route so I'll get to visit the Great Barrier Reef and Ayers Rock, avoiding as much as I can from the rainy north. I didn't know they were so many Australians reading this

-
Zimbabwe: I've avoided Zambia and the route is a bit more logical now. Please,
MountainMan, let me know if I've understood your advices.

India: Yes, you're right,
Stephano. My route was decided only by the Ocean, I did a small ammount of research, and although I'm sure most of the route will be decided by local's suggestions, now it's a bit more logical, I'm including big highlights like Ajanta 1 and Ellora, Jaiselmer, Khajuraho, Mysore, Sanchi, Kolkata, Bhubaneshwar, Varanasi, Goa, and the golden triangle.
SimonR: Transit in Tierra de Fuego is scheduled for December-January. Do you mean in those months I can get snow?. Besides that, being from Spain, I strongly recommend you to stay during the winter in Morocco. Mom lived there (in Larache) and food and weather are spectacular during the winter, and living is extremely cheap. Southern Spain's weather is OK, but living can be a bit expensive.
Please, people, if you have any further suggestions or advices for this route, I'd LOVE to read them.
