This is the Gundam TR-6 [Woundwort] Psychoblade Custom, a minor Woundwort unit.
I was planning to make a modified version, but the finished model turned out so well
I just painted it as is, applied decals, and finished it with a matte coat.
This is an issue with all AOZ units, but the red tips of the hands are a distinctive feature, so it feels somewhat incomplete without painting them. Plus, it's a small area to paint, so it's always a bit of a hassle.
