That dialogue is atrocious! Come on, show don't tell. He really didn't need to say "I've always hated the rain due to my paralysis" when we've just seen him get paralysed in the rain and say "fuck off" to someone who said they liked the rain. Have a bit more faith in the subtleties of your story telling! I think the problem is you chose to large a story for such a short comic, and so the character blurts out unrealistically everything he's thinking so as to reach a conclusion in 1 panel. The story is quite nice, and i like your art style, but you need to think about pacing and dialogue.
