LB2015 : your help please!

This Life Book project was created by Jenny Wentworth. Another face, this time in a more painterly style she called expressive portrait. Pushing my boundaries again - I have never painted in this way before....

I can't quite cope with looking at just brown, cream and yellow so I add pretty turquoise clothing early on!

I quite like her face, but I think I rushed to do "what I know" for her facial features - eyes especially (I've only started drawing faces this year in Life Book Lessons). When I put her next to Jenny's sample (below right), mine doesn't look like the same style at all and I find myself feeling anxious/disappointed/stressed somehow about that...

Does she need more colour and texture, or does this mean I am developing my own style and should leave it there?  Should I watch the demo again and give the lesson a fresh try, or do I just not have this style in me?....
I'm leaving it at least overnight and would love to hear what you think.
