Hey man, i did play your mod.
1. Background image did hurt my eyes

that soily-looking image. i could barely read whats on screen sometimes.
2. Horse sounds did hurt my ears

maybe its just me but i really didnt like those new sounds.
3. Everyone you fight is horse archer in the mod. Thats why i suggest you modify skill points gained at the start, based on your early career choices, to give you more riding, powerdraw and horse archery. You cant invest all skill points early in game to riding/powerdraw/horse archery because you need more urgent things like map speed, leadership, surgery etc. And your companions dont even have Riding skill points

Besides it would make sense that i would have some points in riding/powerdraw/horse archery by default if i am a mongol

4. Bandits are so fast on the map, you cant outrun anyone, they always catch you and force you to fight; its deadly in early game.
5. I recruited all soldiers i could with a new character and been in many fights, almost 20 of them. I didnt have a single bow or arrow in the loot

if what you loot after battle can be changed i suggest you add a whole lot of bows/arrows because every single enemy you fight has bow and arrows.
Now, apart from those i did like the mod. It really has the feel of the steppes if you know what i mean, and fast paced horseback combat is real fun. And the little touches, like makh, adds a lot.
Hope you continue working on the mod cuz it has a great potential.
