Looks great. It's a great design. The bolts at the top of the face shield look a little too modern and out of place for the rest of the design. Maybe something more inset? I love it though. Nice work.
Easy. Just create cylinder with enough sides. The barrel cover has 8 holes, and I used 4 polygons for one hole. so the cylinder needs 32 polygons. Create the holes with 10 similar polygons using the inset function on the 4 polygons and align them... Thanks. I thought about creating one, maybe in the future.
