thanks for the replies ,guys
update i joined the front and back together. i raised the brow up to meet the viser. started on the triangle on the chin. got the place where the viser and helmet meet to go together better. started cutting out the vents to make the wall of the helmet go into the vent like in the screen shots. not just stop where the vent starts. i have also started the greeblies for the breathers but the little filter is under and inch of rtv rubber right now or i would show you. some of the lines are just penciled in.
