Looking for something like a medium voice, that can get both loud and angry but also more soft-spoken for the vulnerable, serious moments within his character-arc. Please try not to exaggerate his voice too much, we're looking for a natural-sounding, sincere performance

Guzma has to work hard to get his anger under control. He tends to lash out on himself and can be frustrated with his own progress. At the beginning he acts cool, reserved or annoyed with a dry tone to his voice whenever he tries to keep others at distance. He has trouble opening up and prefers to pretend to be overly confident, when in fact he deals with a lot of self-doubt and insecurities. Over time he becomes calmer and more comfortable with his friends, allowing himself to be vulnerable and deal with his own emotions better.
