On page two, in the second panel the black haired girl asks, "How it was?" She ought to ask, "How was it?". Just a minor grammatical error.
Nonetheless, thank you very much for your work guys!
EDIT: On page 3, first panel she says: "They didn't even allow me to go TO the graduation trip to Europe." She should say: "They didn't even allow me to go ON the graduation trip to Europe."
E2: Panels 4 & 5 on page 3 have bubbles that are missing punctuation.
