It's possible that Qrow and Raven's emblems are mirror images of each other, forming a pair of winged eyes. Qrow's emblem appeared behind him in Yang's flashback and is on his flask. The emblem Yang drew on the chalkboard was a flipped version of it, and she had been talking about how her obsession with finding her mother almost got her and Ruby killed, so I think she drew Raven's emblem.
