I had this idea... a forest made of all metal scraps. So I started drawing this tree and it ended up being a torturous mess. The effect I created to give the pipes dimension, in cooperation with a light drop shadow (for depth) crashed my computer about a dozen times. So I wrapped this one up and called it quits.
To be entirely honest, it doesn't fit into what I normally like to do, but here it is anyway, my very own Maxwell's Silver Hammer.
