On the Studio Floor Right Now

I've been aching to paint bigger lately since I've been doing so many little canvases since last fall.  I pulled down a 16 x 20 that I wasn't happy with and decided to cover it with big brushstrokes of a magenta shade and was hoping to just see where it would take me.  One of my struggles as an artist is painting freely.  I often think way too much while I'm painting and thinking often gets me stuck wondering what to do next.  I just want to "go with the flow!"  Well as I was letting myself paint big magenta strokes I started make loose shapes and it sort of took on the beginnings of a girl.  Hmmmm...I've always wanted to paint girls but hesitate because of my inexperience painting people.  After I saw the face and neck taking a bit of shape I had the feeling that I wanted her face to be framed with flowers so I got out one of my stencil sheets and put down some light blue flowers.

Then today I added some teal and yellow ones as well.  As you can see, I just haven't taken the leap into drawing her facial features yet.  Something is holding me back.  Not sure if it's fear of doing it "right" or if I just need to see if that's really what wants to be created here.  What do you think?  Any tips for me on the face or should I not even do a face?  I'd love to hear what you think of it so far and where YOU would go next.
