Any ideas?? Aineh (Short Champion information)

I'm working on my first champion concept. I don't have any pictures And I don't finish the lore yet. I give some short informations to know your opinion. Feel free to give any advice or ask any questions.

"To enemy Cassiopeia: Have you ever seen your own eyes???"

Name: Aineh

Role: Mage

She's from Ionia and her power is MIRROR. Yeah mirror. She's surrounded by broken pieces of a mirror and fights with them.

Passive: She gains Ability power per level

Q- Throws a bunch of pieces in to a target(something like Ashe's Q) and it gains stack (like Nasus's Q).

W- Aineh shields herself (or an ally ). And this shield get more powerful with first Ability's stack

E- She spins and the mirror pieces around her deals magic damage to the units around her in a circle area

R- She collects the pieces and makes a big mirror and reflects an enemy's Ability. Like Sivir's shield but with Reflecting an Ability.

Please tell me your suggestions and help me to complete this concept! Thank you~
