I like it a lot and would buy for 975. My only criticism comes from my years of painting minis (dozens of hours on a single 1-inch figure), and it's the same criticism I have with most of Riot's art. When you think you're done, make the shadows one shade deeper and the highlights one shade higher. Dimension is lacking a bit on the bodice and definitely on the skirt layers and leggings. This definitely fits well with Riot's style, but it feels flat in areas.
Some other fun Syndra ideas with cool VFX revisions.
Titan/Geomancer Syndra: Boulders for orbs. Rock spike shoots up from the ground on Q and leaves a boulder behind.
Tempest Syndra: Orbs are stormclouds that occasionally rain and zap lightning as they orbit Syndra. Lightning strikes on Q and leaves behind a crackling stormcloud. Ultimate throws crackling clouds at enemy with long chain lightning zap throughout the animation
Omega Syndra (Ultimate): Named for a very famous omega-level psychic/telekinetic from pop culture. Dressed in a green and black skin-tight suit. VFX start out as pink or blue energy. At rank 5 of each skill, the VFX change to fire. As Syndra levels up, she slowly catches fire. By level 16, her costume is black and red, her hair and eyes are fire, and all of her VFX are fire effects. Of course, she gets flaming bird wings briefly when she channels her ulti.
