Eris the griffin- harpy? Picture

i was looking at some mythological beasts to base a character on, and noticed that a griffin [link] , and a Harpy [link] , have very similar designs when in a humanesque form. Eris started out as a harpy with a more bushy ended tail, but then decided to make it slimmer and lion like so that she could be either griffin-ish or harpy-ish
