Looks:

Winter has very angular facial features, and his eyes are a very dark ocean blue. His scales are dappled with blue and gray, and he has a singular ring on his talon from Snowfall.

Sexuality:

I believe that cannonically Winter was confined Bisexual, and I believe that.

Voice:

Hunter / The Owl House

Other Headcanons:

Winter normally gets IceWing messengers sending him ice sculptures of himself from Mink. They don't look anything like him, and melt within a day or two, but he appreciates the gesture.
