Work in Progress Pepakura Boba // Need Advice WIP // Pic Heavy

Hey everyone! I have lurked for awhile and finally got to a point where I could use some input. I started a pep Boba using Fierfeks pep files and I am now sanding the helmet down. Post fiberglass and resin. Pre bondo.

Here are a few pics of my helmet while it was still just cardstock. Sorry for the mass posting.

Here's one before sanding (it has been resined and fiberglassed at this point):

Here are a bunch of pictures of it partially sanded:

With fiberglass inside it is about 1/4 inch thick.

Fierfeks pep may not have been the appropriate one for me to begin with. I got fed up with a lot of the ear pieces and decided to skip the RF assembly. It was spur of the moment and now I don't know how I should go about it. So:

Stalk ideas?
Do I leave that quarter inch edge at the bottom of the helmet or do most people chop it?
You may notices my right cheek area is f'ed up. It is. What can I do about that?

Sanding and Bondo-wise I think I am capable of doing, but won't refuse any pointers.
The helmet got pretty wavy in a couple spots, but I am confident bodyfiller will work. My main concerns are about the ears because I think they look shoddy.
Lucky for me my dad is working on a kit car and I was able to talk to two autobody guys about bondo and such. Got many compliments on my fiberglass job. So, again, confident I can handle the bondo work.

Thanks all!
