Your lighting is good, and skin tones are nice. I would suggest more relaxed and natural poses that don't look so "posed". Also, try moving your couple further awy from the greenery, so you can blur your background and separate the couple from it.
Quick tip: pay attention to your subjects hands - they can easily break your portraits. Look at how much more relaxed the grooms hands look in #1 vs. #2 & 3.
