Look! I've done something! lol
Trust me, I know it looks ugly, but it's still got a long way to go. Obviously the sintra needs to be trimmed WAY up (I had a bit of a spacey moment when cutting it and cut it a lot wider than I needed but just shrugged and went with it so I'd have plenty of extra space if I screwed up). When I have the money to devote to getting several tubes of epoxy, I'll start work on smoothing out the seams where the sintra meets the helmet, as well as filling in some of those spaces on the helmet that I, well, want smooth. Sintra will probably get a thin layer of the epoxy since I know the stuff I'm getting is incredibly durable and sticks quiet nicely to the sintra. Visor thickness will also be built up, and horns will be added. Still debating how I'm going to approach making the larger horns.
I may be forgetting some steps. Well, I'm pretty sure I am anyway, but right now I'm tired and can't think very coherently.
Technically the second step is shown here; the first was backing off those holes.

I used E6000 for the visor part of the sintra. The clamps annoyed the heck out of me, so by the time I got to the back part, where getting stuff fixed in place was a lot more important to moving forward so I could shape the rest of the sintra, I switched to hot glue. The nice thing about hot glue on the high setting is it actually helps form the sintra into place. The not so nice thing is that there were a couple spots where the overlapping sintra wasn't overlapping by that much and I burned my finger. Oh well, it worked.


Also fixed, as best as I can, that wonky bit you may have noticed on the visor sintra in the first picture. The thing about the 1mm sintra is that it doesn't have much time between barely malleable and omgmelting!1!. So, it's as fixed as I can get it, and the epoxy covering will ultimately smooth it out the rest of the way, I hope. (I've still got to go and try to get a bit more of an even curve in the front, as well as fix how wonky it is around the "ear" parts of the base helmet.)

Here's hoping my ultimate plan works, and at some point in the future there will be more updates.
Oh, yes, and lest I forget, the new feather/bead things I made to hang from the horn of this helmet:
