Seahorse logo for sustainability projects

Description

I need a seahorse logo designed relating to a real life project where we had to rehome endangered seahorses. There was also endandered grasses so I would like those incorporated into the design and a couple of starfish. I would like something elegant and beautiful rather than cartoonish. Could be art deco or art nouveau - see attached. It's a specifically white variety of seahorse found in parts of Australia. It will be used alone as a graphic designating environmental issues/discussion but also will be used in conjunction with a short description of the story. I.e. a blocked image/description graphic I can just paste into InDesign.
