Thanks very much, the crit helped alot
Okse, an artist on twitter/blog TV showed me how to use grids as i'd never heard of them before, and I'm thinking of drawing Van Morrison next using that technique. It might help a bit, like you were saying the nose and eyes seem a tad off, I think thats what the problem is too. I was looking at the left eye before actually, I hate it when there's something wrong that you can't quite pin point! And a couple of people have said about the light and dark contrasts, so I'll go back and fix that too.
Thanks very much
