Wow. They look just... wow. I truly envy your talent. All your characters are stunning! ( Omg it's meeeee!!!! My name's Erin. Just noticed that connection there...)
Some people don't change with age well- My mother looked like she was still in her early twenties, even though she was in her mid- thirties... My grandfather looks about 55 even thoug he's 72. My dad although 40 and Beginning his balding still looks like he's in his early 30's... I'm 17, but I already have worry lines on my forehead- In otherwords, I am not blessed with this attribute.
Your style and motivs is always one positive thrill and feast to look at. Its so charming to see them being together and the good vibes just make my day.
