This one was a pain. Real pain. The surface was totally carcked and broken, and standard airbrush tool was not enough to reconstruct the complex structure of the animal's coating.
Looking at this example you should be able to understand what am I talking about. Thousands of little engraved circles all around the body, and only very few not damaged. First, I tried to build them myself, but soon I understood thet cloning was the only possible way to go. Doing the coating of this and the next animal took me as much time, as the rest of the whole reconstruction.
Missing legs I have replaced by the ones from other animals. Try to guess from which one... Actually not from which one, but which ones...
