A similar suit to the Nu Gundam from Char's Counterattack (the Hi-Nu is not seen in the movie, but is present in the novelisation) - an advanced design that can be controlled by thought, unlike previous older suits which where manually controlled.
I tend to dislike the mobile suit designs with wings, huge add-on fins and the like, so this is about the limit of what I tend to like.
The 'official' blue/purple and white colour scheme didn't really do it for me, so I tried a gunmetal colour instead of the blue. Turned out okay.
Again, this was an early HG model for me; just spray cans, panel liner and the basic decals. However I did really like the way it looked, so I subsequently invested in the MG 1/100 Hi-Nu Gundam ver Ka kit, which is currently sitting in my 'to-do' pile….
