(I've included my older 300 spartan helmet, which is exactly the size of my head made out of poster board and plaster, long before I even heard of this site)
I've finished my pepakura helmet finally, after much procrastination. It is absolutely the smallest size that I think could realistically fit my head (the diameter of the visor is equal to the width of my skull)
Except that be helmet is so damn long. From front to back it is like 2 lengths of my head. I know that is is an exact copy of the helmet featured in the game, but we all know that Master chief isn't anatomically correct.

(the 300 spartan helmet shows how long the helmet is compared to the actual length of my skull)
I've considered removing a polygon loop from the back (I highlighted in red) but I am just wondering if you guys might have any other ideas on how I can change the helmet to just be more realistic in it's shape. I spent 8 hours putting this damn thing together and I'd rather not just make a smaller one only to discover it doesn't fit at all.
Here is a photoshop of what it would look like with that edge removed. I would have to modify the back alot to make it match up.

Input on the matter is welcomed.
