Here is a time lapse of my creative process when creating an illustration. This piece was commissioned by Plugged in magazine. Music by the Odd Numbers.
Basically, I did a sketch, and I imported the sketch into Illustrator. Then on a separate layer, I constructed the content mostly with the pen tool, brush tools and my Wacom tablet. Then I imported the vector piece into Photoshop, and added layers of detail, shadows, highlights and textures.
