Took me about 3-4h to draw Padfoot, Moony, Prongs and Wormtail aka The Marauders from Harry Potter.
Padfoot is Sirius Black
Moony is Remus Lupin
Prongs is James Potter
Wormtail is Peter Pettigrew

Just incase you didn't know who The Marauders are.
If you are wondering why they have animal parts it's because that they are all Animagus.
An Animagus is a witch or wizard who have the rare ability to transform into an animal at will. But you can learn to be an Animagus, but the spell is really difficult and dangerous to perform. So that's why all Animagus have to be registered by the Ministry of Magic. But The Marauders aren't registered. Remus, is not an Animagus because while he was at Hogwarts he got bit by a werewolf called Greyback, and is therefore a werewolf. But Sirius, James and Peter all became Animagus to make Remus feel better.

Sirius' Animagus form is a big black dog
James' Animagus is a Deer
Peter's Animagus is a rat

Just incase you wanted to know.
