Some very nice moments here.
I think in 5 the couple could use a little help with the posing, perhaps having the guy relax backwards a bit with her draped on him.
6 looks really natural - very nice.
8 I think is a nice moment.
The other thing I noticed is that the processing seems to change a bit as the set goes. Looks like it gets more contrasty. That is fine, and both styles look good but you may want to try and create a more uniform look.
