I've deepened the colours with several more layers. I'm beginning to find it easier to see where I've gone wrong - here the tiger's eye is slightly too small and not quite the right shape. Overall though, for a quick piece I'm happy with it.
My optivisor has arrived so I'm hoping that I will find my next piece easier to work on.
I've also booked a place on Karen Coulson's next workshop, which will be a parrot.
