Low Poly Kpack For Kitops - Statues Pro (Vol.1-3)
When I apply a texture I still see some strange shading
This shouldn´t but can happen - if it does, please go into Edit-Mode, select all faces and click "Unwrap", or "Smart Unwrap" - it will fix any wonky shading.
I applied a 4K/6K/8K texture to my model and it has lost it´s Low-Poly feel
This is exactly what happens if you apply very detailed textures to non-detailed meshes. You have to balance the amount of "realism" with the amount of low-poly feeling for yourself. I have found that 0,5 to 2K textures work best, or node-based materials.
