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.
I've been enjoying doing these ACEOs because they only take 2-5 hours, even with that much detail. My realistic art normally takes 10-40 hours. I actually really enjoy doing the details. It almost becomes meditative, but it's nice to finish a few things quickly.
