Nautical but Nice

I am developing some initial sketches for one of my live briefs which I am working on. This brief is to design three greetings cards designs, and a name for the collection. After much mind mapping I decided on a nautical theme for my greetings cards. My collection will be called 'Nautical but Nice'.
I will be developing three sea creatures to base the each card around, and my first I am playing with is an octopus character. Below are the initial ideas for his shape.

I really like the plump, cuter look rather then working with long wispy tentacles, and I think I will be taking forward character idea 3 for further for the development of my first greetings card.

Thanks
