skunk drawing -quick update

This is where i am as of end of the day yesterday with my skunk drawing.it is an incredibly slow and painstakiing business plotting out the tail fur and layering graphite around it to draw it from the paper.so far there are three layers of graphite applied around the tail and once the detail has all been added to it i shall need at least one other layer of graphite to be applied to the background toning before i can move onto the foreground.each layer of graphite is applied using tiny overlapping circles of the  pencil to produce as smooth a finish as possible and takes many hours to complete.this drawing has already taken over 30 hours of work and islikely to be nearer 50 hours by the time its completed.
