I decided to make this type of snowtrooper with this kind of color scheme after seeing the clone wars combatant contest's subtrooper. The helmet is custom casted by me:D and the whole minifig was painted with sharpie by me.
Uh.. Yeah couple things here.. You didn't "cast" this helmet, you just cut the back off, and ruined it with sharpie. Second: You just ruined perfectly good LEGO pieces.
