I think she is doing quite well PRMG, the first thing for me was making sure Dd was happy sitting on the potty (some kids wont even look at it or the toilet).
I found that DD realising she had had an accident in her knickers was one of the first steps to her 'going', also if you give her a big drink, let it settle then let her sit on the potty i find sometimes they just 'accidentally' go IYKWIM.
You could try pull-ups, they look like knickers but atleast if she has an accident she wont be too scared.
