I came across the technique of smoke drawing a few months ago but have yet to try it. The artist would take a burning candle and hold it close enough for the smoke to "stain" the paper. After making smoke marks, the artist would add to the marks by drawing with charcoal. If I can find the info I wrote down I will pass along to you, if you are interested.
This piece turned out nice. The image is almost morphing and moving before my eyes.
I love your style so much ! It's so messy... but it seems like it's done of purpose. Like randomly formulated I wanted to know if I could use this as my Twitter background? I can put a link to your account in my "websites" panel?
