Thank you all!
Found a female Speaker!

The last thing would be a humanoid robot, and be surprised, I got even a perfect picture for you:

Made by terminal26


Of course this is very lowpoly. It should be a lot more detailed,
similar to the "Space Marine" model in the Shaderviewer of 3dgs.
But is puts the whole concept of the robot in a nutshell.
A humanoid, slim "skeleton like" robot, built at 1970 - 1980.
Every bodypart has to be an own mesh, with some sort of joints between them.
He don´t need any weapon atm.
I´ll do the rigging and the animations and I can do the texturing, too.

If you want to do the texturing, he´ll need a dirty and very rusty texture based on photos
of old (1960 - 1980) electronic elements.
It should include a normal map and a specular map as well.

Edit: Take a look at the german :schutzkontakt developer blog and you can see that the project grows nicely.
