First and second layers, I'd prefer less contrast between the two but it looks ok, should be fine with the rest of the layers.
Layer 3 (the gold layer) and part of the blue layer.
The rest of the blue layer. I'm on to the brown layer next. It's much bigger than Eucalyptus Melliodora but I'm pleased that it seems to have kept the same composition and feel :)
I'm still thinking about bugs, maybe a couple of moths?
