The first one has some exposure problems, since the sky is too bright and the aircraft is not properly illuminated (too much light over the wings, but a bit backlit on the fuselage). It´s a bit soft and needs a tad more contrast, IMO
The second one is better, but the exposure issues remain, I guess. I don´t know if this one will be good enough for the DB
The third one is soft, grainy and needs some more contrast.
Hope it helps.
