That's very common especially with dark colors. You probably already have a smaller eye as it is so you don't want to do many dark colors. Eyeliner will close the eye as well, especially if you line the bottom of your eye. If you like doing the bottom only go halfway into the eye from the outer corner. Using a lighter eyeliner color on the bottom of your eye then what you used on the top is great for opening up your eyes as well. I suggest using a brown eyeliner, if you don't like brown do a thin black line and smudge it in, and stick with neutral to lighter eyeshadows, they will brighten up the eye. Use a shimmery white eyeshadow highlight from the lid to the brow and a little bit around the tear duct area to really open up those eyes. Then I would use a light shade and just follow the crease of your eye, you can even go all over the lid with the light shade. You do not HAVE to use dark shades in your eye crease. Use a light shade will make them pop and look wide open, especially after you curl your eyelashes and put some mascara on them. You don't want to go heavy on eyeshadows or eyeliner that will always close the eye.
Good luck!!
