You still have been posting some good pictures but what's going on with your white balance? All your photos are in a yellow-brown tint. I guess it is white balance because a couple of clicks in Gimp gave me so much more realistic look for this particular image.
Please do not get offended and take it as a friendly suggestion from a homie.

Seltsam, aber jetzt sehe ich das Bild, wie ich es für das Beispiel verarbeitet habe. Ich konnte es dir nicht schicken. Hast du es selbst optimiert?
