You may look it as a combination of MANY 30x30 together... LOL
Anyway, the most important things to discuss (concerning this map) are the following:
1. rice fields
2. river bunks
3. dirt roads/path inside jungle
4. density of trees according to height (mountain peak)
5. Mix of talls grass, trees, rough terrain in the mountain regions.
6. Village
7.Huts between rice fields
