Mary-Sue Litmus tests are fantastic tools in general, but unless it's RWBY specific it'll give false perceptions. I'd love to make one RWBY specific but we're all in the same boat. With so little information it's hard to know what's normal and abnormal.

I've always found that a good guide is that good OCs blend with the canon characters where as a bad one stands out, demanding more of the spotlight for being different. Stand Jr and Verdantos in a line next to RWBY and JNPR and see how things go.
