I really like her style, but I would change some things to make her clearer.
* The particles of her Q when hit an enemy are too prolonged, and looks like a Azir's soldier that can attack several enemies with one hit. Just make it shorter.
* When her W is full charged I would add a more evident particle, and change the colour (it does the double of damage, so it is important to know if you are going to receive tons of damage). Besides, instacast W should be faster.
* When her R disappears, I would make some animation or particles. It is a really strong spell (damage, cc and disarm) and you need to know when you can walk through.
This is all. Thank you! <3
