This modpack has over 40+ mods which make the game super realistic. It has been configged to suit the requirements of being very realistic. We recommend you merge forge with optifine (you can easily find a tutorial on youtube).

What you can do:

Better Slabs mod adds more slabs so you can have a slab with every type of block. This can come in handy when building specifically. Bedrock Ores makes it so any ore can be put into bedrock which makes it much harder to mine but it is still possible to mine. Dynamic Trees makes it so that when you mine the bottom of a tree it falls down and gives you all the trees resources instantly. It also adds branches to trees. Dynamic Surroundings adds realistic sound and an ambient reverb to caves to enhance your gaming experience. Biomes O' Plenty adds over 60 new biomes and a few ores. ZAWA adds many animals and exotic birds mod adds many new exotic birds. These animal mods come together to create a realistic experience. Better foliage makes leaves have more depth and parts to it. Chunk animator makes fast travel more interesting as the chunks don't just appear, they seem to move upwards.
