Riot, since you responded for SG Poppy's effects, might SG Lulu & Poppy's eyes be looked into too ?
Aside the fact that they both have blue eyes, i'm pointing at the ingame models having bland grayish eyes while the splash (even if it's mostly lighting effects) are way more colorful...with sparkly stars and stuff. Even Janna has blue eyes like this but because of her model it's not that obvious. Yordles have their huge eyes that is easily spotted ingame and the way it's so bland right now is sad. They should spark as any magical girl should.
I'll make some edits, but i'm really 100% sure purple eyes would still be perfect on SG Poppy (as the splash hints a bit). And also needs more saturation.
