This is my personal favorite of all the Vinyl art I've seen so far. Absolutely love the smile and the way you've done the lighting here. That said, I hate to be a noodge, but have you ever done a recording of your drawing? I'd be very interested in seeing how you work (I'm a bit of a rookie artist and still learning the photoshop ropes).
I appreciate the compliment. To answer your question, no Ive never recorded myself drawing, never felt the need to. If you have any questions regarding Photoshop I will be happy to help to the best of my ability.
