We're the same on loving a dark theme, same here, even my wallpaper has a dark theme too. I mean, they really looks cool and it's good for my eyes. And simpleness is what actually makes it more pleasing to the eyes. Anyways if I will choose one here I'd like the darkest one, it's like an AI image but it actually looks cool, I'd pick the last one, I like the flowers but I like the background the most.
