Espeon: Nope not at all, I wish she was more blue for her shiny.
Jolteon: Its ok not good but a far better looking green shiny than Espeon.
Vanillite: LOVE IT, The shiny couldn't be anymore perfect, the Pokémon is based off an Ice Cream and having its normal Vanilla look turn to a more strawberry look is great!
Audino: I like it, its nothing to rave about It looks cool.
Mudkip: Its ok, most water/blue looking Pokémon tend to get the Blue to purple treatment with their shinies and this is one I can't complain about really, its ok.
Butterfree: I love this shiny, although its nothing drastic Its a great color swap that suites the Pokémon.
Emboar: By far one of THE BEST shinies period, any Pokemon that as an open flame on its body should immediately be change to a bad ass color, blue, purple, its just perfect.
Bulbasaur: Its fine, its just more green although I prefer Ivysaur and Venusaurs shinies over Bulbasaur only because their bulbs are yellow instead of red.
