Work in progress - completed

I posted earlier in my blog a work in progress of a tonal torso, well here is the finished drawing, after many hours of work, I am very pleased with how this turned out as its the biggest I have completed (3.5in x 4.5 in) it took me a long time as I had to keep refinning the tone of it to get the torso to stand out from the background. I am thinking of trying some more tonal studies, bur for a while as I have other drawings I am working on at the moment.
