Advice on learning approach for modeling complex organic shapes

Hello all,

I am a mechanical engineering student looking to model this bird’s beak for university and am currently at a loss about how to approach this project or what workflow I would use. Till now I have only used Rhino for odd projects which haven’t required any subD or advanced surface modeling techniques. I was therefore wondering if anyone had advice on where I should focus my learning, and what workflows and knowledge I would need to undertake this project.
