I know I'm the unpopular opinion, but all of Shyvana's skins suck and I don't think this one is any better. I only say this because...none of them make her look the "the Half-Dragon." All of them just make her some human woman that turns a into a dragon. None of her skins maker look like a "Half Dragon" in away, but her classics ones Splash Art. It's a cool idea and all, but imo, if I'm playing Shyvana, I wanna play a dragon woman, not a Animorph.
I'd argue that Ice Drake Shyvana is actually a very good half-dragon concept. She's still quite humanoid but the ice she has is less something she's wearing and more a part of her.
Her classic skin is still by far the most dragon-like of her skins but there's only so much Riot can do to the small character model without having to completely change the skeleton. In a few years when Shyvana eventually gets a texture update I really hope that they put a ton of effort into the Boneclaw Shyvana skin. That one has one of the best looking dragon forms and there's so much Riot could do with the concept than a pseudo native-american-esk girl that can turn into a dragon.
is the reason I played this game to level 30 and she's still the champ I go back to when I want to live the power fantasy and just have a really good time. I personally own, play and enjoy all of her skins but I totally understand where your complaints are coming from.
