Foam Master Chief helmet.

Had a few hours to myself today so I decided to start work on my Master Chief costume.
I am using my sons halo figures and a lot of pictures for reference, I also using a pep file for some parts. I started taking pics but then unfortunately I kinda got into the build and forgot to take pics.
Here is the back part.

Here is the next time I took a pic, quite a bit done already, this took about 3 hours.

Here is the visoe just taped in to see what it would look like.



For the light holes on the side of the helmet I used an old cigar holder. ( A friend gave them to me because I always like to keep strange and cool things for future builds).
I find using something circular like this is great for cutting perfect holes in foam. I put the foam circles back in the holes for now just to help it keep its shape.
Here are some pictures to show you what I mean.
