I have hooded eyes too. I’m not sure if you’ve seen this post http://imgur.com/a/rqbaM I’m not sure if we’re allowed to post links here but if you google “A visualization of common tips for correcting hooded eyes” it will come up right away. But it was incredibly helpful for me and applying eyeshadow with hooded eyes. There’s also another trick called the straight line technique (or something similar) for hooded eyes which is supposed to ‘lift’ your eye shape.
As for general eyeshadow tips, apply a primer and set the primer with an eyeshadow close to your skin tone or translucent powder. This gives you a smooth base to apply eyeshadows which makes blending much easier. Also when you use eyeshadow try building up colours instead of applying a ton at a time. It might take a while but the results are well worth it!
