Sub designs

So I am knee deep in some new Nemo stuff. I've got some new pages inked so slowly I'm starting to determine the style of the art. But wow is it a tough process. Never quite as good as you'd like it. Also trying to write it. whew! this will be quite a learning curve. Thank God I have the lovely and talented Mark Schultz to help me. It is a bit intimidating to show Mark these pages though, man is he good. So below are some quick little sub designs I was kicking around. The first sub is an amalgam of these. Hey anyone want to sculpt one for me as reference?
