Well, When I mess up, I'll admit it. There was an error in the Kussharo 's SKN File. When it is fix'd, I will re-upload int Art Pack 2.
The other three models are Fine! They are made with different methods than the Kussharo, so they are fine.
The Fan Art Pack is going to be Released with the Fix'd Art Pack 2.
I am also working on Side Specific Art, with a new set of things. Please also check out TWF Models Featured in other mods soon.
Please continue to use TWF for your model needs.
