Work In Progress: "The Oyster Thief" - Part 2

I've added another layer to the rocks, basically just by painting in the darks and defining the edges of each one. I still need to add further definition to them and then add in the sand speckles, as well as to make some look as if they are in the shadows, but it's coming along nicely so far. I'm also still debating if I want to put in my little pink anemone things or the two shrimp I had planned to add onto the large rocks. I don't want to clutter this painting up too much, and I'm worried it might. Decisions, decisions...
