Windrunner is AWESOME as a ginger. The red hair contrasts great with the green, and she's fantastically well drawn; the model looks great, as does the hero portrait. Scarf in particular is awesome.
In addition, she's a cocky ass now, which I love. Windrunner's changes in DOTA2 have been universally fantastic, they've made her even more by far my favorite hero. Gingerrunner rules!
