All three of these make up ideas, mainly the eyes,  are great.I think the first one will be amazing for snake because it kind of shows the cunningness, and is strong, but it isnt like too much. The second one seems real cool for the fox because it has a cleverness and alertness to it, but at the same time there is something subtle to it, and it looks a tad playful. The last one is also an idea for the snake, EYE MAKE UP..not anything else..
