@Amelia-Bothe All three of these are really nice! I really like the lighting and the feeling of all of them. If I have any criticisms I think there are a few tiny areas where things are maybe not quite aligned, which throws things a little bit off. For example, on the first one, the nose is slightly angled toward us, while the jaw looks like it's slightly angled away from us, which makes it look like he's got a crooked jaw. It's super subtle, but it makes it feel like something is just a little bit wrong.
I really like the lighting on that first one, but I feel like there are some other details about the face that might be slightly off.
My favorites are 2 and 3, depending on what mood you're going for, they just have different feelings, so I wouldn't say one is better than the other.
Great stuff!
