I like the first and third ones a lot. the second it looks like the focus was on the plants instead of the couple and the last, I’m not overly keen on the processing. I’ve tried doing these half B&W half colour images myself and I got carried away with trying out the idea and couldn’t tell if the final result even worked. Looking back now I don’t think it did. Just a thought, think it’s a preference thing. I’m no expert.
Nice work on the lighting in 1 and 3.
