Taking shape

After today's work I feel that she is beginning to take shape, though I'll admit it's only an approximation of my reference photo. Today I made a direct comparison on the pc (overlaying the photo onto my drawing and shape wise it's pretty good, with just an error in the depth from under her nose to her mouth however the colours aren't good. Photo realism is something I would love to achieve but I'm a long way from there! Considering that this is my first drawing for about 9 months (and that I never finished the last one), I'm reasonably happy with my progress.
