I'd say #1 is slightly underexposed, and/or needs a very slight "S" applied in curves. Tweaking the position of your lights could avoid the reflections in her glasses.
#2 could do with the subjects further forward from the backbround to lessen the shadows (and if you have a spare light you could use a background light).
Poses are nice, you seem to get on well with your subjects.
Good fun shots..and both well exposed. If you want some critique then watch reflections in glasses (the first shot) think of the light as a pool ball, and make sure it is at an angle where it wouldn't bounce off the glasses into the lens.. For the second shot, if they were a little further from the backdrop you'd lose that distracting shadow..
