Help choosing a template?

Hi all

I'd like to try and make a realistic 3D animal lens, based on this one (made by Snapchat):

Could somebody give me advice on which is the best template to start with? I'm not very experienced, so I don't mind simplifying the lens.

I essentially want an animal's head that moves and also shows the user's eyes. I could also use the user's mouth if it's too difficult to animate an animal's mouth as in the example.

Thanks!
