Paua shell and fossil still life

I am really enjoying Gordon's book and trying not to rush through it! I'll give you a review in a couple of days. 
We are hoping to get Sonica the hedgehog (yes, she's a girl!) back next week to release in the garden as she is now in Hog rehabilitation (Hogwarts?!) at the wildlife centre.
Stuck for a blip today so had a play in the studio with this gorgeous shell from New Zealand and some coloured lighting.
