As I was searching for illustration blogs to get inspiration I found Leigh Viner's blog:
CREATE. What I love the most about her illustration is that, even though it is quite contemporary, it is very classic.
This is my favorite. I love the hair as it reminds me of Klaus Voorman's Beatles Revolver cover. The dark eye, contrasting with the light pink lines fits in beautifully.
For those two, I like the effect of the paint dripping.
The brushstroke in this one is very elegant, giving a light effect.
