I think Riot should do more to showcase the incredible fan art that people submit.

I just checked out the Fan Art tab for the first time in a while and I was amazed at the extremely high quality of everything. I think it'd be nice for Riot to bring more attention to the fan art (perhaps through an occasional link in the client or something like that). It'd be a nice gesture to the artists and it could also generate more interest in the game among the art community.
