Mesopotamian Cuneiform Texture

For this material I wanted to push my knowledge of Substance Designer in order to create a believable tileable representation of Ancient Mesopotamian Cuneiform, one of the earliest known written languages.
I created a node system that generated 30 cuneiform characters, admittedly it became incredibly complex and tweaks in Photoshop were required to help it all come together. I felt I learnt a great deal from this experiment, any feedback is much appreciated.
