I had a dream where I was surrounded by two ten-foot flowers, one of which had a name I instantly knew as the 'Creeping Iris'.
I sketched it out and began to love the way it was looking.
I sharpened the design to give it a 'penned' feel and attempted to clean up the background and was...somewhat successful.
Then I airbrushed some color over the bits, attempting to darken the shaded areas and give the impression of depth without losing some of the deeper color schemes.
All in all, I believe this is one of my favorite sketchbook doodles.
