Blender model lighting issue (modders help please)

[Serpentis]

So, I was going to make some sigs and some other graphic stuff in PS, so I fixed the models I wanted to play with. But each .obj with texture I import has this weird lighting issue (despite making a new light).
In "Texture Paint" option in blender it loads the model and texture perfectly.

But when I try to render the image it comes out weirdly.



Like this.

Any modelers that can help me with to solve this issue?

Cheers
