since I did this based off a photo with a Creative Commons license this is free to use under certain conditions.
the photo I referenced can be found here: http://en.wikipedia.org/wiki/File:Mustela\_nivalis\_-British\_Wildlife\_Centre-4.jpg
the conditions for the Creative Commons on it are:
attribution – You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work).
share alike – If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one.
what I ask is that you let me know if you use this and link back to this deviation or my account. if you add a background to the colored finished product do not use anything that isn't your own work, under a Creative Commons license, or you didn't ask to use. do not sell the final product or prints of it either.
