I've been working on the MS-06R for a while now, and I've been sanding it nonstop lol.
It's often said that the best 1/144 Zaku head is either this 06R or the one that comes with the Zaku Tank.
The beautiful curves live up to the rumor. Since I'm planning to finish this as a Gaia unit, I've drilled holes for the blade antenna.
I drilled holes with a pin vise in preparation for attaching an action base.
The bottom of the feet have quite a bit of unevenness at the seams, which makes them tricky to work with. I scraped them down.
