Looking very cool so far. Quite amused by the giant pig head breathing flame haha.
So far it's kinda hard to see what the effect is, I'd encourage you to focus more on the effect first then the presentation (Env, character, camera work) after.
The fluid like flames in the second gif are looking quite flash but perhaps too big? That is the tendrils may be too large causing the rest of the scene to look smaller (Could also just be perspective thing though)
Regardless keep up the cool work
