Hi. I have finaly created something i am actually not embarrassed to show.
I will probably not make any changes to this image, but feedback for future work is highly welcome.
Nice modeling!
But in Future, you could care a bit more about lightning 
e.g. more colorful lights, like light blue and orange
just like the lightning in this tutorial:
Blender Cookie 16000
lights are set up at 37:40 min

Thanks for the input. Yes lighting is still a big issue with all my work. I tried to go with: http://www.blenderguru.com/videos/mastering-lighting but i did not play with colors.
