I asked about the origin of the medallion over on the Aurora form, a few years ago. One of the members stated that the piece was definitely Lugosis' personal property and that it was Masonic. This would explain the star and crescent motif.Great job. As for the orignal prop, the dragon motif is in line with the historical Dracula (whose father was in the Christian Order of the Dragon), but the Star and Crescent, a Turkish symbol, seems odd considering how much Dracula hated the Turks.
Giving it more thought, and thoough probably oncly coincidental since it seems this was Lugosi's own masonic medal, your design actually makes good heraldic sense as the dragon's aura is blasting away the Turkish/Muslim star and crescent symbols.The crescent and star motif was copied from photos/screen grabs of the original prop while the design within the circular center area is open to some debate due to a general lack of details so I took a creative liberty and incorporated a more historically-accurate Vlad/Dragon treatment.
