Your Avocado photo stands out to me the most, being in black and white. I think that having this as your main photo would accent the coloring/tones and the sense of detail very well. The other three photos are in color, so they would look well paired together not only because of this but also because they have a constant theme of nature throughout. Overall, all 4 photos show great attention to detail and capture the viewers eye in a unique way.
