As promised to Sancho here is an update. I now have most of the dome and cheeks main details done. They have the SP Lark Gray around the scratches so things are moving well. I am going to go back with a fresh eye and ref pics to make sure I didnt miss any small silver peices. (The main sratch details that further the weathering will be added with a colored pencil once all main detail for the helmet is done!)
The main silver sraches were done with stencils I cut my self, the gray was done by hand.
The helmet is still lacking a few silver scratches on the back and one on the top... then the green is done!
Next I will do the upper cheeks and the back. I am saving the red for last.
