For me, the eye twinkle that Qrow had while fighting Winter was actualy Branwen family semblance. My theory goes something like this:

Yang can absorb damage and attack back with incresed strengh. Her eyes changes color to red and her hair glows. Ravens semblance is unknown, but somehow her weapons and appearance looks same to Adam, so that makes me think they could be related. Adam can absorb damage into his sword and deliver a powerful attack. His hair glows. Eyes cannot be seen.

When Qrow is fighting against Winter, he gets hit (probably only hit during this encounter) and immediatly after that gets the eye twinkle. His next attack suddenly tears a big hole in the ground, wich none of his strikes before that did. That makes me think, that he can counterattack with an increased power immediatly after he is hit.

Looks like to me, that all these characters probably have semblances with the same theme of absorbing energy from enemy blows, but with a different spin.

Youre welcome to poke holes into my theory.
