WIP Fire Character For Class (Critiques)

Urgeo

Looking for critique of my simple fire character i am making in class.  Specifically I need advice on the texture but critique topology is appreciated.  The character will be a enemy that could one day go into a unity project.  model

Updated model with an idle animation, which you can see in the sketch-fab on original post.  Having a lot of trouble with vertex normals.  The face animates with multiple textured planes that are set up with driven key.  I managed to remove the hard edges around the eyes but I just cant seem to get the normals around the mouth pieces to work.  Anyone have advice on editing vertex normals in Maya?
