Hi....I am not an artist but I have an idea of Easter Lux
Here are my thoughts of her:
She has on a top with Bunny Teemo on it and at the back of her top is a Easter egg
She wears a short skirt (above the knees)
Those socks that are as long as to the knees with colorful stripes
She is holding a wand (handles are stripes of rainbow color) with two eggs a each point
Passive: a Easter Bunny/Bunny Teemo is running around the unit's head (:P)
Q: the snare will shoot 3 Easter eggs in a row and if it hits...it will flow around the target or whatever/whoever it hit
W: she throws a Easter stick with 2 Easter eggs on it.....the shielded person will have a Easter Egg around them
E: she launches a Easter Egg from her wand and when it explodes.....you will see sparkles/sprinkles.
R: fires from a Big Easter Egg in front of her which shoots out (Liquid) chocolate
Please have her look smexy from the idea given or you could make it some what like what I said.
I hope you got a clear mind of the details given.
