Interesting tree. I don't find this particular photo of it all that compelling, but that doesn't mean you shouldn't go back and work with it. In various types of light and from different perspectives, I can imaging it being mysterious and fascinating. Regards the DoF question, there's no technical data regards focus distance and focal length you used so it's hard to respond. Say you're at 10' distance and FL = 20mm, which looks likely ... DoF at f/ 4 for that setting is 19 feet, 3.8' in front and 15.4' in back. And in a small, web-resolution rendering, sharpness falloff in the distance is going to be subtle. So it's hard to get much distance blur at those settings.
