Custom Mandalorian First Time build

Hello,
I'm fairly new to the whole building costume armor scene, but I've always been a big fan of Boba Fett and the Mandalorians, so i decide that I would try and make my own armor. Granted I'm working on a budget so I had to make most of the armor using the cardboard method and lots of glue.

But here are my results so far


I used the cereal boxes to make the plates smooth before priming, but I have no idea what to do for the helmet, so any suggestions would be greatly appreciated.

You should search for helmet templates in the search bar. There are tons of helmet build ups for reference! Good luck with the build.

thanks, only thing is I don't intend to use fiberglass resin or bondo on my helmet, of course I would love to, to make it last longer, but at the moment I don't have the time or money to do so. I hoping there was a better why to prime it so the tape and all that would not be showing. Or a way to fill in the gaps that are around the plastic helmet on the top that I'm using for the dome?

Well I finished most of the costume with cardboard, sorry my computer put all the images in sideways for some reason
