Skyscape Step 2

This is a 6x4 foot canvas, the biggest thing I have attempted painting since I was in high school (some 8 years ago).

Step one was painting on a thick layer of sky.
This is step two, painting on the backmost layer of clouds.

This is done with liquitex acrylic paint on a 6x4 canvas that I built myself out of 2x4's and some duckcloth from Joann's.
