Your champion concepts?

I've been looking at the art concepts riot has put out before they release champions or champions that are in progress and I wanted to work on my own concept drawing of characters that real players think would make awesome champions in the future. I know there's probably about a thousand ideas that people have had rolling around in their heads for what would make the best future champion and I wanted to know what exactly (from lore - physical attributes) other players thought would make an awesome addition to the league champion select? -- Just looking for ideas that would be cool to sketch
