Loading 3DS file model in Unity with extra elements

Hello, I'm trying to load this model from 3DS into Unity: https://drive.google.com/file/d/19rNYfnIaUkdjzhLhEtaWrM4tqlYi09yg/view?usp=sharing

But it seems to be having issues loading properly the textures, if someone could help me that would be fantastic.

I also need to add some more paintings and 3D models from Picasso I will provide.

Thanks,

Arnaud
