Not only did I find the free to use base yesterday, but after requesting a head-only variant for icon use,  may825 was generous to provide one, which I am very thankful that she made one! This is now my current icon for a undisclosed amount of time. The headshot variant is located here: [ http://www.furaffinity.net/view/24003007/ ], in the lower portion of the comment section.

[Program used: Paint.NET 4.0.16 (coloring edits, sky background, and additional fur details via a PS brush plugin)].
[Estimated time of completion: 10 minutes, due to me copying the layers from the full-body version and lining it up with the headshot base].
[Eye detail was done via a vector image of an actual Iris, but heavily edited to work on the base].
Enjoy!
