You dont have to apologize for that your English isn't so good, I am sure of that your German is better then most of the English peoples here;)
My advices to you is to get Photoshop and use "auto levels" on this picture, do a cool background and do something cool on the base! I think the mini looks really good for being your third mini, so a little more practice and you be a very good painter.
Auf wiedersehn!
