Nice work Andrea! The images are very thoughtfully composed and you can feel the emotion between them. Great work!
I would love, love to see what you come up with when you add some lighting to the mix - flash, reflector or off camera. These images would go from great to spectacular!
Other than lighting, my only other critique is to keep an eye on background elements. It looks like in the first image, just a slight adjustment of your camera angle would have hidden the address numbers on the house. It's not a big deal (and your friends won't even notice), but it's little details like this that will make your images standout and look extremely polished.
Overall - great job! I love seeing your work. :)
