This is Miss Pin, Nurse at St. Mary´s School for Wayward furs.
Color version, all here is my personal impression as an artist,

Pin is © by  makojin, all errors are my personal ones since she had nothing to do with the making of this pic. Thanks to her for creating such a nice character and letting me draw it. ^_^

I used Paint.NET to color this, nice program and free! ^_^
