Maokai Champion Concept Art Rework

I'm going to preface this with the fact that I know I'm a little late on the draw here. I hardly every have any form of criticism for Riot and the work they do on the champions; however, there is a first time for everything. I've recently been playing a lot more of an old favorite of mine, Maokai, and I just can not get past the cartoony appearance of his character. At first I thought it was my graphics, but I began talking to some of my friends that also play Mao and they agreed with me. Is there anybody out there that can get Riot's attention on this with some better concept art for them to implement for him? I know this isn't a "high priority" deal, but it is something I would like to see improved at some point.
