a draw for some riot points

to get actual assistance with your RP request, submit a support ticket with the art and request since it's an account-related thing. Good luck![slayer-jinx-catface]

needs more

well that's probably because this is the section to share fanart/user created art with others. I'm guessing you probably posted it in the story, art and sound section or in help and support. That was from the board moderators though, not account-related riot staff, so you should still send a ticket in for your rp request to get reviewed by the right team.
