Heavy Assault Space Marine

A friend of mine has his own Chapter color scheme for his tabletop Space Marine figures, he calls them the Argent Knights.
I needed a paintjob for this model and ran out of ideas, so I decided to do a tribute to his little guys, following his metal-and-blue color setup. He had an idea for their logo, a laurel-wreathed sword, but no visual examples of it, so I had the honor of realizing that.
The shield and gun are leftovers from my Source engine days, upgraded with PBR and detail maps.
