Time lapse drawing - 'Flower Head'

Hello friends - I hope everyone is having a great summer. Inspired by the lushness that's blooming in the countryside at the moment, I have created a drawing called 'Flower Head'. Here is some sped up footage of me working on it. 

For this piece I used a hard lead pencil ('H') for drawing in the basic shapes, then began to fill in and add tone with softer pencils (2B and 4B). Next, I used black pen (a fine tipped liner and a fine tipped Bic) for definition and depth. Finally, I scanned the drawing into the computer to add colour.
