I didn't even notice the glasses! (Yeah some art beta *I* am! lol)
But ya know, in lots of stories Harry gets his eyes fixed. It never really made a ton of sense to me that they could regrow bones but he had to wear glasses...
Regardless., what I look at first are the expressions and they were lovely. So happy and warm and in love. The scene was pretty, the tree was pretty but what I really enjoyed was the 'light' in their eyes if you know what I mean...
