We Zyra mains, though small, are a devoted fan base, even though we are aware that Zyra receives little in regards to skins, which is nothing to say about her lore(I'm still hoping that with the release of the new flower mage, we will get some lore on Zyra). While it has been made clear that Zyra is a champion that deals with a lot of textures and other minor things and details on her model that accumulate to making it quite difficult to make a skin for her, it has been a year and a half since the release of her most recent skin, Dragon Sorceress.
These are concepts made by a Riot employee, Riot Hylia to be specific, and all I can say is why not use these? They were made nearly 4 years ago, and he works for Riot, surely Riot must have at least seen them, so why not use them?
Personally, I'm more in favor of Mythic, due to it probably being the easier to make, and because I always feel weird using an event skin outside of the event. Like, using Santa Braum in the middle of July.

This is the link to Riot Hylia's artstation page, he does a lot of League work, and it's all incredibly detailed.
