Pufferfish Design Ideas

I decided today to do some concept art for the project's pufferfish protagonist. As far as is known to science the only known species of puffer that makes the patterns in the sand that so inspired us is Torquiguener albomaculosus, more commonly known as the Japanese white-spotted puffer.

     Although I have not entirely nailed down a specific design, I decided to make a pattern contact sheet. Even if this is not the form that sticks, I hope these designs can remain transferable. I looked into making something distinct and perhaps show our fish might be creative in some way. But because of the inspiration I also looked into making something that could be described as cute. So I'm not entirely satisfied with designs 1 2 and 3 on the upper panel.
