Your definitely a skilled modeling artist. The only change I’d make to your fox character is to the eyes. Your Fox character, he’s the ‘Indiana Jones’ of Foxes, the ‘Adventuter’, the ‘Danger Additct’, he lives life on the edge in order to feel alive as he indulges in one of his adventures into the unknown. He’s just dropped down into a tunnel, where he knows danger lies at every turn, where either doom or destiny lys in wait for him, so he’d be a naturally suspicious individual, I’d chance his eyes to have a look of ‘suspicious curiosity’ rather than big wide-open eyes
