Nice job, may I ask what part you used?
For Starkiller, here's the parts:
Head = Starkiller (Toys R Us 5-pk)
torso = Concept Ki-Adi Mundi (TLC) -- heavy mods on the neck area
kama = Borsk Fey'lya (TLC Comic Pack)
arms = GIJoe POC Duke (jungle gear)
right hand = EVO Count Dooku; left hand = Luke Skywalker (Endor Capture) -- allows to pose Starkiller's saber more freely in the manner he holds it
legs = Hoth Han Solo (Saga Legends)
feet = GIJoe ROC Kamakura
