Reality Valley is a realistic high resolution texture pack which works really well for medieval worlds. The textures are extremely detailed and almost overwhelming if you're used to the vanilla textures. All blocks appear to have new textures but there are some mobs which don't have new ones such as the husk. It's compatible with all platforms but it's best suitable for high-end devices.
