BB - 8 Star Wars 7 [WIP]

Hey guys so lately I’ve been working on this droid. For now I am finished but I need to go back and post process using the nodes in blender but here’s what I have after 14 hours of work.

Please bare in mind I have never used cycles node materials or textures before so it was very difficult as I could not find the suited tutorials for materials so a lot was just delved straight into.
