Defining my nose

Here i am in the process of defining my nose and other characters on my face like mouth and eye lids. To do this process i shaped the nose a bit more in low poly modeling mode and then created a few more edges with the cut tool round the nose. I then used the create tool to put a polygon where the nostrel is and pull it up inside the head to create a void ( nassle passage). A few more tweaks and it will be there, just have to do the eye lids and mouth with a similar technique.
