process of this drawing - http://blog.loish.net/post/79583068924/self-portrait-turned-out-a-bit-cartoony !
For this image, I used photoshop CS5.1 in combination with a wacom Intuos4 tablet. The brush I used was the standard 'oil pastel large' brush that comes with photoshop, with flow on about 16% and opacity on 100%. I started out with an A4 sized canvas. I drew the image using a mirror as reference.
