Noxus Poppy should have red particles.

Owning both SG Poppy and the new skin, it went on to make me realize how bad the rest of her skins were in regards to quality.
I always thought it stunk that had Poppy been 6 months later then she had, she would of seen so many changes to her skins. Instead she got no changes to any of her skins.
I always thought Noxus Poppy was a great skin, but it's visual effects always clashed so hard with the proposed theme, and I thought amongst all of her skins it was the one that had the most potential.
