A necron conversion "How to make a warrior to a flayed one"

I had three warrior models from a scrap model Ebay offer . They had broken weapons.
So I diced today to change them to flayed ones .
I start by cutting the weapons from the hands.
Then I cut some plastic pieces , in elliptic form like a claw.( I cut them from a DVD plastic case ) and I glued them on the hands , three in each hand.

 On this one I put a chaos marines head stuck on necrons claw . 
After that  I painted them with Bolt metal and Rotten Flesh , a thick layer of paint  where supposedly there was flesh.  

  At the end , I painted them with  red paint for blood .And painted the head of that poor Chaos Marine .

I think they look nice for a friendly game , don't they ?
