Inconsistencies with Rework Poppy's Handedness.
Going through the Splash Arts and the newly released comic, I noticed something that I find fairly interesting. While it isn't 100% consistent, art depictions of Poppy overwhelmingly favor her as being left-handed.
Classic, Noxus, Rag Doll, and Battle Regalia picture Poppy as left-handed. Blacksmith, Scarlet Hammer, and Lolipoppy picture her as right-handed.
4 out of 7 in favor of left is a majority, but still, probably not conclusive enough. That's where the comic comes in.
By my count, Poppy is displayed as clearly favoring her left hand 19 times, as opposed to favoring her right hand only 5 times. This one in particular shows a very clear trend towards being a left-handed fighter, with the other examples being few enough to perhaps be an oversight, or, if intentional, show that she is ambidextrous to some degree, but largely favors her left hand regardless.
However, the game model tells a different story, as she holds and employs her hammer exclusively with her right hand. One could argue that her impeccable aim with her left-handed shield throw is another show for ambidexterity, but even then, her model overwhelmingly favors her right hand, being that it is where she holds her hammer.
In Summary: Poppy is [primarily] Left-Handed in art, but Right-Handed in game.
Personally, I like the idea of Poppy being the newest addition to the under-represented lefty club in League (which I believe currently only consists of Taric, Dr. Mundo, and Ezreal).
and his Q ability icon!
It shows it as a left hand on the icon, but it actually fires his right!
