Every player has his own favorite and least favorite Shiny Pokemon I think, and they have different opinions. I like to buy . For me, any shiny that is not obvious Shiny disappoints me, and Froslass is a good example.
Froslass hardly changes color at all, the most obvious change is the color of the sash, and then the icy spots on its head and sleeves are a little darker, just so bland. I think a shiny should be noticeable, just like Diglett and Dugtrio, the main changes are their noses, and different shades of brown for the fur.
In fact, for most players, it is not easy to capture a Shiny Pokemon in the game. If you want to get a shiny that you like very much, the easiest and fastest way is to choose a reliable website to buy it. PKMBuy is such a store where you can any you like.
