Only as a hint, Urs, in the about box it should be "Bitte nicht" instead of only "Bitte".
Anyway, the image does possess that "live" quality of some moment frozen in time, and the coloring is OK, but the overall implementation and composition makes me miss many things, like for example the strong differentation of the front and the back, perhaps some line leading into the scene, and the like. It's special points are represented too weakly this way.
... The candidate has passed the test, 100 points: You are perfectly right: "Bitte nicht füttern" is written there, which means: "Please don't feed". When I shot this picture I did not see the sign, I only recognized it when I was seeing the picture on my computer, and it made me smile ... :)
Thank you for commenting mny picture, Naomi. Best wishes, Urs
