@mferster : Thank you very much ! I think it is due to the HDRi's I use. I do them myself by the way.
@agentdark45 : Thank you ! Glad you like it ! :D It is just lit with one HDRi, maybe you know it "Creative studio" I got it from Greyscalegorilla. They are directly from the VFB, so no editing afterwards.
@yagi : Thank you ! I use my own Hdri's that I shot some time ago. There is a good tutorial where you can correct a hdri so that can be used as the only source of light. This is how I work with my scenes.
