I've been renovating Hg Nobel gundam as the basis. Specifically, not only The Nobel Gundam, but also other Gundam parts were used for renovation. There are also self-made parts made from epoxy putty.
Super cute. I gotta get back into Gundam model kits eventually. Also I just noticed those lego pieces. Radicon got me again.
i would have recomended useing the core gundam 's arms as the arms. they should be small enough with the added bonus of a double joint
