Hopefully you will find this as constructive crit in the way it is intended.
Photo 1.
The couple is under exposed. There is something weird going on with the hair on her neck. The crop could be more powerful.
Photo 2. Overexposed. Nice moment, but it's ruined by the overexposure.
Photo 3.
Nice. Make it Pop and you have a winner.
Photo 4
I don't understand what's going on, but not a bad shot.
Photo 5,6,7
Noise Noise Noise. None are bad, but all are flat and noisey. Can use use a noise program on these? They are cute photos. I see big potential for the last shot.
