Idea 1:
The orange hair is a subtle change that brings out the fox ears just enough to make them a bit more noticeable. The black is more dramatic and slightly changes the overall appearance of the avatar, but still looks nice too.
If you want to keep the hair color red, then I'd suggest you use a style that's a bit flatter up top like Rain or Wildflower. You know, so the ears are the only things sticking out of your head.
For sunglasses, I like how the Romani ones look the best.
Chairo isn't bad either, and they're a bit cheaper, if I remember.
If you want, I can suggest some hats after dinner
