I love seeing drawings of little mundane scenes that aren't mentioned in the books but would fit into the series canon and feel totally right. This is one of them. And I love the details in your drawings, like the paintings and the chess pieces here.
I always love SO MUCH in your pictures, but things I like best in this one are: How animated your characters are, it's like you've taken a snapshot right in the middle of it all. Ron and the Twins' expressions are so funny! Googly-eyed Trevor sat behind Harry. The hole in Ron's sock. You've managed to even give the tiny chess pieces personality! Magic monopoly
