HTML/CSS assignment: Almost done?

Hi Everyone,

I think I am very close to being where I need to be with this assignment but I am not 100% sure. The border is on the image and the hover shadow functionality works when I hover the mouse over it. The only issue is that it all changes on me when I expand it where the border and everything else goes away. Am I ready to submit it? I feel something might be missing. Thanks so much!
