What can I do better? Do I need contour?

Hello everyone, I've recently started posting on Reddit wanting to look & feel better in everyday life, and I've already gotten some helpful tips (I didn't really know I have hooded eyes which I've learned on here!:)) I'm just not very good at makeup. I don't own contour and I wouldn't really know where and how to start, I tend to get overwhelmed when I look up tutorials. Maybe you have some tips for me in general or about that, I'd love to great your thoughts!

I'm not wearing any makeup on the 3rd & 4th photo.

I use a bb cream from essence for my case (German drugstore product) Mascara is by essence, too I used the elf mad for matte for eyes Maybelline superstay for lips, rose dust
