There are of course some shades that absolute duds that need more work to build up pigmentation. Generally a lot of good pigmented colours in there and it seems to be going slightly in order with my swatches on how pigmented they are.
As for the glitter it's quite chunky and surprisingly not as gritty in texture as I immediately thought. However you will need quite a creamy base for the glitters to adhere, as they will just leave you lids and cause fall out.
(As you can see when you scroll down I didn't use any base for my swatches)
