Here's one drawing that didn't work out.  Pity, as I thought it was going OK.

I don't know this actress (Sofia Grabol) but saw a photograph and loved the shape of her face.  She has a very long face and I discovered quite late into the drawing that I had made it too wide and too short.  I started to make the adjustments but it just didn't look right any more.  I'll pick this one up again later but meantime I've started work on a drawing of Ronnie Wood from the Rolling Stones.
