Ghost Rider

 Here's a small model that my wife and I did for a conversion contest; I did the conversion and green-stuff, she did the painting. 
This started out as a Space Marine Scout Biker, because Ghost Rider doesn't wear Carapace Armor, I swapped out the torso for an IG torso from the tank accessory sprue, shaving off the Aquila.  His head is from a WH-FB Skeleton Warrior sprue.  His whip was made from a tow-cable off of the tank accessory sprue.  All of the flames were added using Green Stuff.
