Here's a close up side view (using the Macro setting on my camera).
I did a bit of cloud sponging on the white card stock, I dragged my vanilla craft pad across the Creamy Caramel ark and drew lines & nail heads with my black marker, some more sponging on the ark, and I used the slit punch to make the waves and sponged them too.
Here's a tip: For the "ark" shape I had to be a bit creative. I didn't have the right size coluzzle and couldn't use my GIGA circle punches on this one so I used a saucer from my kitchen cupboard to trace a circle. Then I cut it in half and added the "ark" details.
