Finding the right tutorial for my eyes: Monolid or Doublelid?

Hi everyone! I’m a newbie and I recently got into makeup, and been trying to find the perfect eye makeup tutorial for my type of eyes.

Yet I can't seem to figure out whether I have monolids or doublelids or hooded or whatever. I've asked a few people and researched online, but they’ve given me conflicting answers, so I thought I’d ask you all to help settle the debate!

Note: All these pics were taken at the same time, just various levels of the angle and “openness” of my lids.
