To get colours to show brighter : try Urban Decay Primer Potion or a similar base. Apply with the wand and blend with your little finger, denser nearer the lashes and smeared more thinly up towards the brow. One "wand worth" does each eye.
Look carefully at the pic of yourself with open eyes here, just to try to understand your eye shape, and you'll see with eyes like yours, the two eye parts that are most visible when your eyes are open are the lid part closest to your lashline,and the skin just under your brow. Just try to take this into account when you experiment with makeup: as these are the bits you can see most, clearly these are the bits you should play up with more colour and drama..... So one look would be to use a neutral colour on your lid, but something with a bit more colour and lots shimmer under the browbone area (a pale, sheer gold for example), and a brightly coloured liner on your top lid (bright turquoise? purple? glitter liner?), very dramatic retro "cat eye" black liquid liner will look great too.
At the same time, don't forget, people see your closed lid much more often than most people realise, everyone blinks several times a minute without realising it: therefore if you put a bright, glamorous colour on the bit of your lid that disappears when you look at yourself straight on, it will still be visible to others - more visible to others than to yourself. I think it can be a really cute, fun thing to have brightly coloured lids that people see just in those little "flashes" when you blink! For example, you could do a really intensely dark, rich, shimmery purple eyelid "smokey" which looks quite sweet and innocent face-on (as just the little edge of colour at the lashline will show), but when you blink every now and then people will get just the most amazing flash of that lovely rich colour.
Another look again is to take one colour - your main colour - across your lid and blend out high enough that you can see it just a little bit when your eye is open. Then with a darker shadow, draw a deep "V" on the outer corner extended out beyond the edge of the eye just a little bit, and blend it only gently, keep it quite strong... I use this one quite a lot, I think I pinched it from snowkei (who's stuff you should check out, she's amazing) - it gives the illusion of a nice sexy cat-eye shape to the eye area, and that colour will be visible.
HTH! I have quite small eyes, and use all sorts of tricks to make them look bigger, and I also do eyemakeup for my boyfriend quite often, he suffers from "disappearing eyelid" syndrome big style so I'm just sharing the bits and pieces that I use on us both.
