Now this was going pretty badly for a long while. I thought I had a plan after yesterday which was to keep the shadows from going too green and just use mainly cerulean. Not much was going well but suddently something magical happened. I was about to abandon ship and thought 'I'll just put the darkest shadows in and see if that helps any'. Oh boy did it help! Everything suddenly started coming together and I ended up with something where I feel I'm getting somewhere.
Now - there's still a way to go. But phew!
