A Little Art for Myself

I have always loved horses, and for the lull in between setting up portrait commissions, I search the internet for images of interesting subjects to practice drawing techniques and materials. 
This particular horse I have not been able to find again. The first time I found it was almost 2 years ago, I'd like to at least mention the photographer. I printed out a copy on multi purpose paper and carried in my sketchbook with me, so that I could draw during times I was waiting, like my son's guitar lesson or while oil changes or services on the car were being done.
I was just tickled how well it turned out and continued to work on it for several days after one particularly lengthy scheduled service on my car.
The detail below was after the first day, and since has been cleaned up, but I still like the fuzzy sketchy look and decided to post it as well.
I used a combination of Prismacolor Turqouise pencils and Staedtler mechanical pencils, and of course loving the tortillion and kneaded erasers.
It is drawn on Strasthmore Sketch Premium Recycled 60lb paper.
