I created the Strike Freedom Nishiki by mixing the MGSD Freedom Gundam with the HG Mighty Strike Freedom and the RG Strike Freedom Freedom.
The MGSD Freedom's wings are large, making the RG Dragoon look small.
There are quite a few small differences, so I gave up on some of them...
The MGSD Freedom has a frame structure that allows the waist-mounted railgun to be rotated backwards, so a Strike Freedom version will be released soon. 🤭
(The railgun can be rotated backwards so a rifle can be attached to the waist, but this feature is gone on the Nishiki...)
