Making something look 3 dimensional comes from understanding the basic shapes underneath the surface. For example, a basic upright tree trunk without the branches or leaves or bark details is a basic cylinder. Understanding how a cylinder is shaded means you can translate that into a tree trunk. The same can even be said about the smaller branches, which can also be considered small cylinders. If you can master shading cylinders, then shading a tree will be a lot easier to understand. Naturally, there are also other things to consider, like the leaves and the texture of the bark, but taking it one step at a time will bring you one step further to your goal.
