They look fine! I'm not gonna be sad over possibly better shiny palettes because it ain't gonna change anything and lots of other Pokémon got this treatment. shrug I guess (and you can always make fanart with your own colors after all. official shiny color ain't gonna stop people from doing that) I think I mostly don't wanna get disappointed for something like that
Honestly I am not keen on that copper colour...it looks washed-out and generally low grade effort. Like a lot of shinies, admittedly. It's by no means the worst - not even a hint of green, after all - but it is far from the best.
I actually really like the coppery look. It may look extremely similar to the original coloring, but when you have Pokémon based off of nuts and bolts, there's only so many varieties of colors out there to use that'll still make it look natural.
I'm going to be honest, I'm disappointed in the coloring of the shiny cause I don't like it when the shiny looks a lot like the original.
I mean, look totally fine to me, as a Pokémon I prefer it to the original, as a shiny I thinks it's just a bit too similar to the original, And, I just love the blue electric wire-like tail <3, such a cute detail to this shiny in my opinion x3
Reminds me of Zygarde core in the anime. The normal colour scheme was green with a red core inside but there was a second one that was green with a blue core. They also have the kind of merging gimmick.
