I've been working on these for the past couple of weeks (anyone who's been around here for a while will know I've been obsessively drawing Paul for the last eighteen months in the hope of improving my ability to a capture a decent likeness) and while I've discarded a handful most of them have actually turned out OK! Screen grabs from interviews are great for practising expressions. :)
As usual, I recommend clicking and enlarging the pictures to see them properly; they look better that way.
