lens from top?

[HERB]

i have my lens about 7 inches wide, is that about right?

 

and I'm putting it about an inch below the visor

 

Just wanted to make sure i had these dimensions about right before i got there! thanks in advance!

i got these dimensions from the yoda scene when a scout turns to commander gree so the helmet is facing directly towards the camera (so to speak)

 

i set the distance of the inside darker area of the snout to 1.5 inches (the area with the mouth grille) then measured from there but im wondering if anybody else would share what they have, im building this suit from scratch
