For Bormac :D
It's true, lobsters aren't totally red when they're alive. They're more of a black/brown, mottled with red/orange underneath. (Rarely, genetic mutations have been found which are gold, or blue!)
Setting is an underground cave and ocean lit only by phosphorescent moss. A perilous path of stepping stones is the only way to get to the entrance of the stalactite 'tower' about a mile out, but it's easy to slip and fall into the waters. And the water is far from still.
It's funny how I got two painting commissions at once that were both about fleeing from something! X3
