Dog drawing progress

ive spent a couple of days working intensively now on the head of the dog with graphite and blending stumps to reach this stage.i'm happy that,all bar a couple of tonal tweaks,the head is now finished.The body is going to require a lot of subtle blending and 'lifting out' of highlights from within shadowed areas to bring out the shape and form and then finally some heavier shadowing around the dog to lift the whole drawing.Hope you're all enjoying the process and i'll be back with more soon.
