Textures not appearing on models

[Piefihi]

I don't have any previous experience in modeling or in making textures. I have scoured the internet to see if I can find a solution but can't find out why the textures just don't work on this model. The texture only works for the face.

Idk if this helps but I got the model and texture from the mod that turns ashley into hatsune miku and am trying to apply both over leon and if I can get it working, over every enemy in the game because the thought's just funny. If anyone knows how the textures effect models in game that would help a lot.
