o.o Wow, this is amazing! You make me so jealous of your coloring skillz! XD Would you mind if I drew from the photo a pen and ink version? I'd give you credit for showing me the photo, and I'd also site your drawing if I upload the ink fox to DA x3
Actually, I don't have an original photo to send you. You are welcome to reference my art piece directly, but I looked at a few different photos before drawing this piece.
Other than that, there are a lot of very good photos of foxes in the stock images gallery. Quite a few show a clear view of the eyes. [link][link] Also, I have found that most of the nature photographers do not mind traditional artists referencing their photos, as long as the artist asks first.
