How did you do that!!!!!!!!!! 
I just recently thought of doing something like that. I am amazed. This to me is art work. Please try to explain in detail what paint you used and the technique. If you could give a shove in the right direction that would even be a help. Great work. 
Here goes. I will explain as well as I know how. It is really easy, so do not be afraid to jump in and get with it.
1. I went to Walmart and bought the Krylon Camo brand in primer, tan, olive, brown, and matte finish clear coat. It is on the same shelves as the other spray paints are.
2. Take and wipe the gun down real good with rubbing alcohol. This will rid the surface of any oil residue from cleaning and handling. Take the recoil pad off, and tape off anything you do not want painted. The only thing I taped off was the number dials on the scope ans used a razor blade to cut for a clean straight line.
3. Take and hang to rifle from the trigger guard with some heavy gauge wire or string. Get the primer and paint the whole rifle. Now this is where you can mess up. Here is the way I spray. Take and start the spray off the gun and run the whole length without stopping any where on the gun. This will eliminate any running or over spray in one area. Do this until the whole gun has a fine coat on it. It may take several coats to get it completely covered. Just remember do not rush as to cause any runs. Let it hang for about 1 hour after the last coat is on.
4. Next, paint the whole rifle in the tan color the same way you did the primer. Let dry for about an hour.
5. Go find you a fur tree and cut a sprig off about 8 inches or so to use as your template.
6. Lay the sprig where you want it and use the olive and brown to spray swaths over the fur sprig all over the gun. You want to spray enough just to give the outline of the template. Let it dry for about 30 minutes and turn over and do the other side. After you have fished the pattern to your liking.
7. Take and hang the rifle back on the wire and spray a good coat of clear coat. And your done.
Now if you have the wood stock you will want to take a fine sand paper and knock the finish off to where the paint will take hold.
