Pakal, King of Palenque
This is a digital drawing based on a mural from a Mayan ruin in Palenque, Chiapas, Mexico.

Process:
I used Adobe's Ilustrator Draw app on my iPad Pro for this drawing.
After completeing the Line Art Drawing, I added a black layer which I superimposed on the Line Art layer and erased lines to reveal the drawing underneath for a woodcut engraving effect.
After the Line Art drawing is revealed, from under the Woodcut layer, the two layers are merged.
I added a beige layer under the Line Art layer.
I added a reddish brown layer as the background color and light blue accents to the drawing.
