The conversion itself was pretty cut and dry. The head for the biker is from the Vampire Counts Coven Throne/Mortis Engine kit. I used a spare hub cab to give a base for the skull to rest on in the neck socket. I used a heat gun to bend the tendril of smoke around the backpack and create a sense of forward motion to the figure. The axe is from a Chaos Dark Vengeance Chosen.
The flame are a combination of a Chaos Spawn tentacled head and several sets of spawn tentacles. The tentacles were glued to the wheels and arranged in a way that was aesthetically pleasing and created a sense of writhing flames. The flames were painted by brush using a basic blending technique, working from dark green to a light green until the final highlight is nearly pure white with the touch of light green.
Whilst flames in small areas aren't terribly hard to sculpt, flames that writhe and snake out are very tricky. Using the tentacles saved precarious amount of time. And since this was a nurgle style chaos lord I felt like the tetacles for flames really worked with the style of the model. You can almost imagine the flames writhing with a life all their own.
Although the traditional Ghost Rider comic book super hero has flames surrounding every inch of the tire, I felt like localizing the flames to a few locations got my point across with going overboard.
