A while ago, Heroes of the Storm website had an interview with Trevor Jacobs, Assistant Art Director, and Andrew Kinabrew, Senior Artist, and they've talked about the creative process behind creating new skins and other content for Heroes of the Storm.
That was when we first had a chance to see concept art for the new skins and mounts for an event with Ancient Greek Mythology as a theme: Zeus Cassia and Tracer Hermes skins, as well as Cerberus and a Pegasus mount.
And now, on the same evening as Dark Nexus II launch, Blizzard shared final models of the skins and mounts of this Greek Mythology themed event (via page Héroes en LÃnea).
