'Some descriptions say their faces are apelike, while others show them with beaked visages more like those of tortoises or with duck beaks.'
Yes they do have duck features, Golduck is also based on a kappa if you didn't noticed yet.
Anyway about Ludigator itself, I don't like it that you brought the features from Ludicolo back, the hat and the hair, which are its main features. Instead you should've started from scratch. Transforming a Lombre to a completely new evolution while forgetting about Ludicolo.
