4th company champion

This is my first attempt at kit bashing to create a new model. I love the company champion but hate how few options the champion has. This is supposed to be a unique unit....not some rank and file marine! This champion is for my Imperial Fists 4th Battle Company. To create him, I used Sternguard legs and torso, right handed power sword and left handed combat shield from an assault marine, champion's shoulder pads (I figure since that is a really unique shoulder pad, it should be the one thing that truly identifies him as a champion) and the backpack from a metal Pedro Kantor. I'm still debating on the head, the one shown is pretty much a place marker until I decide what to use. I have a few resin heads from Anvil Industries I might see how well it looks.
