Ouch–I was thinking of the wrong legend. ‘Hide’ a thumb inside the seal skin, then. As far as the background goes, sea is tough. Rocky promontories can be cobbled together for interesting shapes. Embiggened capes and hair do pretty well. That’s part of what I did for my ‘The 2 Explorers’ background. A vague ship shape hidden by fog is something you might do very well, based on some of your pieces . . .
