The first pic looks best! It has a rich natural look with a hint of warmth.
The 2nd & 3rd pic have a washed out look, making the viewer feel a bit chilly.
The last pic of the headlamps in the dark would be very hard to depict which car it came from, good thing this is the E90 forum.
Overall I see how your trying all kinds of styles out and the effort shows. Great Job!
I really like the exterior pics you took, especially this one is my favorite!
