I've bottled out of some of my more ambitious ideas and kept it relatively simple, and to a theme.
I love the light coming through the water and onto the ocean floor - so here's a literal interpretation and a repeating pattern developed from my tutorial which I wrote a few weeks ago.
|Acrylic on paper, A3|
|Shells drawn on paper with a fineliner|
Pattern created in photoshop, then coloured.
Ripples added as an extra layer.
