Idea for a league of legends champ. I'm awful with coloring and shading, any ideas for coloring and if anyone could help me shade or point me in the right direction I would appreciate.

It's a yordle afflicted by the void so I wanted to stay true to the purplish theme, made the character more feral in appearance, also a yordle that has undergone too much isolation and due to it's interaction with the void it became blinded and it developed a taste for fear, screeching so loudly that it makes the manliest of men cower which puts the yordle into a craze(something I would want incorporated into the champs passive.)

I'm thinking it should be a jg assassin, with health pool as a mana source, and some sort of passive lifesteal in it's kit. Thinking of an ult similiar to Cassiopeia's cone-shaped screech but to be an aoe fear instead, with a double cast, one for charging up the ult and the second for release, you would be able to jump during this ability's charge up period.
