Hey Ruze, I'm liking your Carter helmet, but I think it's a little narrow. Here's a quick pic that might help...
There may be a way to scale just the width of the model in whatever program you're using, I calculated about 115%. Other than that it looks great. I can't wait to see this one finished. Looks like it's going to have a lot of the correct features that the model I pepped didn't have.
