So after my game on Saturday, I decided that I need to model up a Farseer on a jetbike as that seems to be a nice option. I have a bunch of old jetbikes that need to be refurbished, so I took the bike and cut off the wings on the back.  The body was taken from a guardian model (a female one at that), the head and right arm are from a Dire Avenger Exarch, the shield vein thing on the back is from the Wraithblades, and the wings on the bike are from the Crimson Hunter.  Pretty happy with how it came out.  If I were to do it again I would try and find another head that looks more farseerish as my conversion only looks alright.
