you don't look squinty eyed to me.. but you have oriental type eyes.. so the proper placement of your eyeshadows might help too.. one colour all over the eyelid and a highlite shade under the brow and down towards the tear duct should work well.
Lou's suggestion of light liner on the waterline would help too - a skin colour is my preference.. also, don't line the lower lid with black or dark browns.. use a bronzey brown or a soft plum.
good luck!
