Moses and the Burning Bush

I suppose there are a lot of ways of depicting fire in a line drawing.  I looked at many photographs of fire, and of course not only is it evanescent, but it is ever-changing, and has a different appearance depending on the wind, on what is burning, and on circumstances that it would take someone more knowledgeable in physics than I to explain.  My aim was for the fire to be beautiful and flowing.  I looked for some inspiration to Aubrey Beardsley's gorgeous forms in black and white, those Art Nouveau shapes wherein Reality takes a back seat to pure line, but in the end Mood predominates.  I didn't want to make a moody image, but I did want the fire to have that elegance of line that is so much a part of Art Nouveau.
