I'm working on a creative project that has brought me into the world of taxidermy and am working on a modified Fawn, so my question may seem unusual for experienced practitioners of this craft so please realize this is for a conceptual art piece and not a traditional mount and no disrespect is intended. I'm looking to make this fawn appear "aggressive" or "fierce" so I'd like to have it showing its teeth or "snarling". Unfortunately I couldn't find any open mouth fawn forms (working with a standing closed mouth) so I'm trying to figure the best way to create the mouth that would help represent this. I realize this is an unorthodox question. Any helpful suggestions or advice/input is welcome. Thanks in advance.
