Pushing Daisies Caricature

I'm trying to get more extreme with my caricatures. This is an attempt at Lee Pace who plays Ned on the show 'Pushing Daisies'.

Also, I recently indulged in an hp laptop which has a monitor that swivels and works as a cintiq, but there are giant differences in what i see on that screen in comparison to how the drawings appear on regular screens. This one, for example, had lots of nice shading on it on my laptop, but on here it just looks like a mess. I wonder how one goes about calibrating these things...
