She's beautiful, I can't wait to see her in colour! Her mane and tail look luscious, so sleek and pretty.
I'm a huge watercolour fan and I think their softness would suit the elegance of the picture.

Acrylics may be a better choice if your paper doesn't like wet techniques, though. Whatever you decide, I'm sure it'll look gorgeous when finished. Looking forward to an update!
