Coincidentally, in the Studio, I had a couple of artists working on small portraits starting with a colourful background.
Often the fear of the blank white page gets the better of you and you need something to break that obstacle. My favourite solution is to "mess - up" the canvas with some random colour. Then I can go on and improve on the original under painting.
This portrait was done as a demo in the class.
Two birds with one stone and all that...
So here are some progress shots from the demo:
Quick lines to find the face
A lot more could be done - the fingers remain very vague and the eyes could also be refined but I've decided to post this so it's still a WIP.
