Horatio would definitely see her potential and think her a prized student in Ravenclaw for her musical/artistic abilities, but he wouldn't think she was that awesome of a witch. He looks out for the great ones and he wouldn't really think she'd cut the bill, but he would be impressed with her birch wand. Also, I think he would really annoy her because they definitely don't see eye to eye on the issue of equality. He thinks people are naturally unequal and that it's preferable that way. He'd view her opinions on the subject as childish but cute.
