This painting of two slipper lobsters hiding in coral was a great exercise in precision. I learned by doing the left-hand one that too many details obscure the image- a wet tissue erases easily, leaving only areas of color. Details are then re-applied judiciously. I knew instinctively when the lobster on the right was done as soon as I got the expressive eye and the fringes in place. The blue ground anchors the piece.
