Both of them are almost too cute here for words. I love Bruce swishing his cape like a flamboyant matador, Jason stuffing his face, Jason's incredibly puffy hair, just Jason's expressions and body all around.
I love this style of drawing where the body language etc. is sort of...what's the word? It's just that it's so clearly done. A lot of comics today seem like they're more realistic but I like people striking poses that show what they're feeling.
