Experimenting in Blender - Dead Tree

I've decided that I'm going to try and have a play around in Blender at least 3 times a week outside of my Udemy courses to get a feel for the controls, how to utilise shapes properly and to mess around with numerous other tools as I learn how to use them.

Today I made a dead tree.

The first image is the final render with a light emitting background to show the contrast better and the other two are without the contrast and without the texture.

I'm not entirely happy with it, but it's progress!
