Thanks for your comments!

After the "semester break" (which means no holidays) I will have more time and try to get some experiences in a professional photostudio. Here in Wuerzburg I can rent one. Then the distracting background shouldn't be a problem.

Sure, Wuerzburg is nice, and here are many places to take pictures from.

Klainmeister, did you worked there or were you on holiday?

Greetings,
Stephan
