I'm afraid, Photoshop is pretty expensive indeed. I only could use it because my brother is computer scientist and has lotta good programs too. I'm lucky even I didn't really deserved it.

Made a new picture. The colored version of "The Interpreter".
Left: Original Size (I actually worked with this size to make the details better. Especially to draw the lines clearly.)
Right: Smaller Size
