I say "almost" because there is still some fine tuning and clean up I need to do on it.
I will probably cover some of my mistakes up with masking tape and them paint it.
This is the center mowhawk piece. I had trouble cutting it to the roundness of the top of the helm. I had to move a pencil along the top of the helm as I held a piece of paper behind it to get the curvature, and it still wasn't exact.
Here's the back. The mowhawk piece was supposed to go all the way down to the red part but it wasn't long enough. I added a piece of cardboard there to make it look like it does go all the way down but it leaves a crappy looking gap if you look at it from the side. I hope to fix that.
Here is the helm in its almost complete state.
On my head it looks like it's going to be proportional.
