I followed Maggie Stiefvater's drawing advice. More or less. Only with some slight distortion for the final project - who needs values, after all?
The 20 second value sketch took me 3 minutes, and the line drawing 5. The painting took me hours, not sure how many. More than two, less than five?
And yes, I tried to find a raven to honor her writing, but morguefile (thank you mothdevil!) fed me crows instead, and called them ravens...
