Light a candle, cast a shadow

We did smoke paintings about a month ago and I forgot to post the results. Paintings were made on Mat board and core boards. Light a candle and use the smoke to create a charcol finish on the board.

  Then paint around the smoke with paint colors that enhance the image made with the smoke. I believe I used paynes gray, and yellow orche.  There may be some antwerp blue and quin gold.

The 1st painting is over worked, and the second is not done. Where you see just gray needs to be made into a shape. I would like to make a couple of big rocks. Yes, I am scared I will over work.
