I would like to suggest you add a landscape texture mod to support full parallax terrain to be loaded before Vivid Landscapes. Personally I use Skyrim HD - Terrain Parallax Tribute 1K version and think that is great but I also recommend looking at aMidianBorn Landscapes which might be better suited to this pack, they are both different styles, but equally well suited to this pack and I think either makes a very nice improvement. If you dont want to use parallax terrain, maybe you should tell users to set fixparallaxterrain=false in the ENB as there are currently too many textures not compatible with it.
