The Angel was to be covered mostly with his wings. But all the way I drew all his body, and then deleted, leaving only his exposed parts.
Or I could not have drawn hime other than a turtle, thrusting the limbs from the wings.
I set the background color in dark red, because my image of the scene is always volcanic. Namely,
in the Bible it is written that Isaiah went to the mountain, (<- It was my mistake, Isaiah saw the holy existence in the Temple of God. I should have confirmed it in the Bible. ) which I always imagine as a volcano. Maybe the word "red hot" invokes such an idea.
Thank God for giving me the power to finish my humble picture.
