I am new and would love to join!

I'm posting 3 characters and the artist can choose any one of them, although am I allowed to request that Chimalsi should not be drawn with Aa Moja or Rangi?

Chimalsi: http://lionobsession.deviantart.com/...-Ref-470350723
Aa Moja: http://lionobsession.deviantart.com/...Moja-478226075
Rangi: http://lionobsession.deviantart.com/art/Rangi-478436928

Thanks and I can't wait to get drawing!
