Here is an animaiton of a dragon head I modeled and added my (limited) knowlege of the fire/smoke simulator.
Looks good 
Although I don’t think fire tends to look that way when it’s ‘shot’. It seems to be moving too slowly and generally in that situation it would appear more like a jet of flame rather than a moving fire. In a quick reference picture I found you can see the way the fire is projected and then expands into the ball of flame / fire that you have:
