ein foto wurde abgelehnt und ich weiß nicht warum

Most likely it was rejected for Quality/Technical reasons.

Your composition & preparation could have been better. In the future, practice stepping back from your subject to give it some space. 

For comparison, this is another Wayside Shrine in the Alps.  The photographer stepped back to give the shrine some context.  Notice the difference?

Hope that helps.

Cropped too tightly and the lighting is too uneven between the deep shadows and strong highlights. Taken at a better time of day would have helped.
