I was experimenting with acrylic inks. I used a process where you drop acrylic ink onto the watercolor paper and spray it with water. Then you lay something on top of the wet ink. It could be anything you want, to leave an impression in the ink. I used saran wrap and wrinkled it up in various places. When it dried, I took off the saran wrap to see what it looked like. Then you can embellish it with other paints, or whatever you want. When I took off the wrapping, I wasn't sure how to finish it. It wasn't really "speaking to me", so I put it aside for over a year. One day, I got it back out and turned it various ways. Horizontally it looked like a landscape, with reflections in the water. Vertically, I saw an angel, with it's back to me, as if God was calling the angel to give him his next assignment and the angel was answering back..."Coming Lord!" I added some gold metal acrylic liner to accentuate the wings and body, so you could better see what I was seeing.
Ps 103:20* Bless the LORD, ye his angels, that excel in strength, that do his commandments, hearkening unto the voice of His word.
