Good work Davide,
I liked the map although here are some remarks(based on first look):
1. Nice topography, you respect the morphology of the ground
2. Good use of tall grass on the right side of the map.
3. You should reconsider the use of impassable terrain inside the jungle/forest and in general in the map.
4. The use of lines in any natural formation rock etc... must be the result of a specific reason (water, wind etc...) Be careful about using lines in natural formations!
5. the recreation/simulation of the trail in the forest should be made with earth/mud instead of sand. Also try to avoid lines in the trail; it is better to put an obstacle somewhere in order to create turns and corners!
more comments later, but my overall impression is: excellent map.
ciao,
Pyros
