DISCLAIMER: I'm in no way associated with the Guy who made Ashen texture Pack. 

For me the Ashen Texturepack Is really Immersive, So I decided to make a modpack to complement it. This is a slightly hefty modpack  Due to the bigger world generation and the added structure., I would recommend 7GB to 9GB of ram to run it comfortably.

This Modpack does't change up the gameplay a whole lot. It just changes structures and makes the world feel more alive.

What to expect?

• The Ashen Texture Pack
• New Structures
• More Animations (Players / Mobs)
• Mob AI Improvements
• Optimization 
• Dynamic Lighting
• Better camera movement
• First Person Player Model
• Better Structures (Big Villages)
• Structures are Further Apart
• You Have a Corps When you Die
• Seasons 
• Tempature 
• Fires are Unlit / Go Out
• More Vanilla-Like Food
• Roads Connecting sertain Structures 
• Better world Generation / Biomes

I would heavly Recommend using the Ashen Texturepack ToT
