About animation snag-boos - maybe his will be blink his eyes and something in his mouth maybe happen (for example - tongue of fire or just move tongue )) )
And about from - more principal in form (light, shadow) and less detail in dark piece. This quick edit.
About you flying character - I am not sure about his wing. If this wing of dragonfly than more blurry frame (we not see him form, but see they move). Or they is a bird wings? than paint more frames with fluent move and we see his from more distinctly. I hope you understand me )))
It's good staff!
