Hi Jamie and Mattias,
Thank you both for your comments. It's wonderful to receive such positive feedback.
Jamie, the rifle stock was base coated in Vallejo Orange Brown and then added small overlapping dashes of wet dark brown and orange brown pastel chalk over the "wooden" surfaces. I then spray Dull Coat over to seal the pastels to the surface and then did the usual highlighting and shading with acrylics. The pastels help to create a very pleasing wood grain finish. I'm glad you liked it.
I haven't watched "Band of Brothers" for years. I watched "Patton" and "The Battle of the Bulge" for inspiration on the uniforms worn during the Ardennes offensive. And yes, the helmet needs more mud splatters IMO.
Mattias, thanks for your comments and, yes he certainly does look like a young Clint Eastwood. I used pics of Clint from "Kelly's Heroes" as reference when I was painting the face.
Brass buttons are standard issue on the M1938 US Overcoat, although buttons on the later version M1943 Overcoat (I think) were made of Dark Olive Green plastic. The buttons on this bust have a cast eagle on them, which means they are from the M1938 Overcoat and should be painted brass.
