since youre new at this, custom morphing faces from scratch is likely out since its not a simple matter to completely remorph the eye area.

youre much better off picking up a premade character thats close to what you want and then further morphing that to customize it.  pretty much everything here comes with commercial use rights.

...or try one of the Aiko figures at Daz - theyre manga-ish variants that come with 'the big eyes' :)
