Animal Drawings within Drawings

An artist that has a passion for animals and the environment, who is trying to do something to help.
Australian based, graphic designer Nathan Ferlazzo, has this to say about his art:  "I drew these illustrations to support the protection of Australia’s Great Barrier Reef. A share of profits from every print sold is donated to Great Barrier Reef Legacy".
I mixed some of his projects, so I don't know if the statement applies to all of them, but it's nice to see people giving to causes they are concerned about and want to do something to change things.  Great drawings, super detailed with multiple "picture in picture", some carrying doodles and the rest, carrying other animals.
