Hi EB II team - and thank you for making this mod. I'm very pleased and excited to be playing. In this post, I am going to praise you (I'm not here to complain). However, there is an important detail missing: the Zagros mountains area is much too flat. The Zagros mountains is a mountain range that separates Iran from Iraq, running from the Persian gulf all the way up inland towards Armenia, to the east of the Tigris and Euphrates rivers.
I had a look at the Alps for comparison, and I see the Alps are beautifully modelled - in fact I'd say this mod has one of the best mountain ranges I've ever seen in a Total War game. Your Alps are wonderful. So all that needs to be done is to make the Zagros mountains of Iran look much the same as you have done with the Alps in Italy. For comparison, the Alps highest point is 4,810 metres, while the Zagros is 4,548 metres. However, the Zagros is nearly twice as big as the Alps, due to it covering an area of 533,000km square.
The Zagros are not some minor hills, they are one of the largest and most historically significant mountain ranges on planet earth. They also played a huge role in human history; some of the earliest evidence of human cultivation comes from the Zagros, which was part of the fertile crescent even as far back as 7,000BC.
The Zagros include some of the greenest areas in Iran, having lots of rivers and mountains. The Zagros mountains certainly shouldn't be depicted as a desert (I'm not saying they are desert in EBII, I'm just mentioning it because some other M2TW mods got this a bit wrong) - that said, you probably could do with some big oak forests near Shiraz, as that area is famous for its oak trees ). Here's some photos to help.

And here's a map (for those interested) proving my point about the amount of rainfall the Zagros receives:
What this is telling us is that the red, yellow and brown areas are as green as Greece - 380mm of annual rainfall. In fact, the red and brown areas are considerably greener, with up to 1,500mm. The areas marked green on this map have about the same rainfall as central Anatolia. These areas are more green than dry. The purple areas represent areas where desert covers at least 25% of the land.
An area with 300mm of rainfall is a climate somewhere between Greece and central Turkey.
