The HGUC Superior Gundam has been reworked to improve its proportions, details, and range of motion, giving it a color scheme reminiscent of the MG renewal version.
Just finishing the seams and painting them was quite a pain, and it's a bit of a tricky thing that doesn't move very much, lol.
Even after the modifications, there are still interferences and it doesn't move very much, lol.
It's a pretty cool kit even without assembly, though.
