Initially I wanted to make a more complex and complicate matte painting than I have done so far. I exaggerated a little the difficultness and at the beginning I said to myself that it was a hard challenge to put an octopus in it. For the octopus I found approximately 40 photographs and then I chose among them. All the tentacles and the head are from different octopuses.
