Harlequin style Cronos Parasite Engine or Talos Pain Engine

I found an old Harlequin Wraithlord on Ebay, unpainted and in perfect condition. I debated for a long time how to put it together, should I convert it to make it look like it's actually armed with the Cronos or Talos weaponry? In the end I figured I would mostly use it as a Cronos, and it has similar weapons, a big gun on the shoulder and a flamer.

So I kept it as sculpted. I just bent the arms and legs a bit to make it look like it's running.
