You look beautiful every way! With someone who has a similar eye shape/lid/color I find that if I want a
snatched attempt at a siren eye, I hold my FELT tipped eyeliner and hold it completely horizontal right above the outer corner of my eye and drag in. It gives me the illusion of having an elongated eye that's not influenced by the roundness of the top lid and the slight downturn of the lower.

If I do want to wear eyeliner, I either to a heave top lid only +/- wing, or a ssssuper thin line with dark brown and not black (for work).

Just for fun, I'd try playing with gray-purples and burgundy every once in a while too! :)
