Your attention to detail is awesome, I love so much about these two! The knuckles, finger detail, her dimples, the noses, the mouths, and his toes are amazing! However, in some areas I think that while you are enjoying the details you are neglecting some larger aspects such as the shape/anatomy of the legs and arms. With all of the character you are able to put into the hands, feet, and faces; I would love to see you further it in the structure of the hands and even the knees. I can't wait to see what else you do and how you progress!
